CVE-2021-29647 An issue was discovered in the Linux kernel before 5.11.11. qrtr_recvmsg in net/qrtr/qrtr.c allows attackers to obtain sensitive information from kernel memory because of a partially uninitialized data structure, aka CID-50535249f624. LOW Apr 5, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3470 A heap overflow issue was found in Redis in versions before 5.0.10, before 6.0.9 and before 6.2.0 when using a heap allocator other than jemalloc or glibc\'s malloc, leading to potential out of bound write or process crash. Effectively this flaw does not affect the vast majority of users, who use jemalloc or glibc malloc. MEDIUM Apr 5, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-30004 In wpa_supplicant and hostapd 2.9, forging attacks may occur because AlgorithmIdentifier parameters are mishandled in tls/pkcs1.c and tls/x509v3.c. MEDIUM Apr 2, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3421 The signature header is not signed, but some data is extracted from it and incorporated into the RPM database. It may be possible to insert an erroneous and/or malicious OpenPGP signature into a signed package this way. It is possible to inject strings into the RPM database that the owner of the database would not wish it to contain. -- Mar 29, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3450 The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a purpose has been configured then there is a subsequent opportunity for checks that the certificate is a valid CA. All of the named purpose values implemented in libcrypto perform this check. Therefore, where a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A purpose is set by default in libssl client and server certificate verification routines, but it can be overridden or removed by an application. In order to be affected, an application must explicitly set the X509_V_FLAG_X509_STRICT verification flag and either not set a purpose for the certificate verification or, in the case of TLS client or server applications, override the default purpose. OpenSSL versions 1.1.1h and newer are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1h-1.1.1j). MEDIUM Mar 28, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3449 An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j). MEDIUM Mar 28, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-29265 An issue was discovered in the Linux kernel before 5.11.7. usbip_sockfd_store in drivers/usb/usbip/stub_dev.c allows attackers to cause a denial of service (GPF) because the stub-up sequence has race conditions during an update of the local and shared status, aka CID-9380afd6df70. MEDIUM Mar 27, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-29264 An issue was discovered in the Linux kernel through 5.11.10. drivers/net/ethernet/freescale/gianfar.c in the Freescale Gianfar Ethernet driver allows attackers to cause a system crash because a negative fragment size is calculated in situations involving an rx queue overrun when jumbo packets are used and NAPI is enabled, aka CID-d8861bab48b6. MEDIUM Mar 27, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-28964 A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer before a cloning operation, aka CID-dbcc7d57bffc. LOW Mar 26, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-28972 In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. This occurs because add_slot_store and remove_slot_store mishandle drc_name \'\\0\' termination, aka CID-cc7a0bb058b8. HIGH Mar 26, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-20271 A flaw was found in RPM\'s signature check functionality when reading a package file. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package, whose signature header was modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is to data integrity, confidentiality, and system availability. MEDIUM Mar 26, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3466 A flaw was found in libmicrohttpd in versions before 0.9.71. A missing bounds check in the post_process_urlencoded function leads to a buffer overflow, allowing a remote attacker to write arbitrary data in an application that uses libmicrohttpd. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. HIGH Mar 26, 2021 None (Wind River Linux LTS 19)
CVE-2021-28971 In intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c in the Linux kernel through 5.11.8 on some Haswell CPUs, userspace applications (such as perf-fuzzer) can cause a system crash because the PEBS status in a PEBS record is mishandled, aka CID-d88d05a9e0b6. MEDIUM Mar 26, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3444 The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure (kernel memory), and possibly out-of-bounds writes that could potentially lead to code execution. This issue was addressed in the upstream kernel in commit 9b00f1b78809 (bpf: Fix truncation handling for mod32 dst reg wrt zero) and in Linux stable kernels 5.11.2, 5.10.19, and 5.4.101. MEDIUM Mar 24, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-28375 An issue was discovered in the Linux kernel through 5.11.6. fastrpc_internal_invoke in drivers/misc/fastrpc.c does not prevent user applications from sending kernel RPC messages, aka CID-20c40794eb85. This is a related issue to CVE-2019-2308. HIGH Mar 21, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-27170 An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit. LOW Mar 20, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-28660 rtw_wx_set_scan in drivers/staging/rtl8188eu/os_dep/ioctl_linux.c in the Linux kernel through 5.11.6 allows writing beyond the end of the ->ssid[] array. NOTE: from the perspective of kernel.org releases, CVE IDs are not normally used for drivers/staging/* (unfinished work); however, system integrators may have situations in which a drivers/staging issue is relevant to their own customer base. HIGH Mar 20, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-27171 An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-10d2bb2e6b1d. LOW Mar 20, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-28831 decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit on the huft_build result pointer, with a resultant invalid free or segmentation fault, via malformed gzip data. MEDIUM Mar 19, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-27928 A remote code execution issue was discovered in MariaDB 10.2 before 10.2.37, 10.3 before 10.3.28, 10.4 before 10.4.18, and 10.5 before 10.5.9; Percona Server through 2021-03-03; and the wsrep patch through 2021-03-03 for MySQL. An untrusted search path leads to eval injection, in which a database SUPER user can execute OS commands after modifying wsrep_provider and wsrep_notify_cmd. NOTE: this does not affect an Oracle product. HIGH Mar 19, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-35492 A flaw was found in cairo\'s image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo\'s image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability. MEDIUM Mar 19, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3428 The Linux kernel\'s ext4 file system implementation contains an integer overflow that can be triggered by mounting a crafted file system. The problem occurs in ext4_es_cache_extent(), when lblk + len exceeds 2^32. -- Mar 18, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-35519 An out-of-bounds (OOB) memory access flaw was found in x25_bind in net/x25/af_x25.c in the Linux kernel. A bounds check failure allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. -- Mar 18, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3448 Use random source ports where possible if source addresses/interfaces in use. -- Mar 18, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-35521 A flaw was found in libtiff. Due to a memory allocation failure in tif_read.c, a crafted TIFF file can lead to an abort, resulting in denial of service. MEDIUM Mar 12, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-20232 A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences. HIGH Mar 12, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-21300 Git is an open-source distributed revision control system. In affected versions of Git a specially crafted repository that contains symbolic links as well as files using a clean/smudge filter such as Git LFS, may cause just-checked out script to be executed while cloning onto a case-insensitive file system such as NTFS, HFS+ or APFS (i.e. the default file systems on Windows and macOS). Note that clean/smudge filters have to be configured for that. Git for Windows configures Git LFS by default, and is therefore vulnerable. The problem has been patched in the versions published on Tuesday, March 9th, 2021. As a workaound, if symbolic link support is disabled in Git (e.g. via `git config --global core.symlinks false`), the described attack won\'t work. Likewise, if no clean/smudge filters such as Git LFS are configured globally (i.e. _before_ cloning), the attack is foiled. As always, it is best to avoid cloning repositories from untrusted sources. The earliest impacted version is 2.14.2. The fix versions are: 2.30.1, 2.29.3, 2.28.1, 2.27.1, 2.26.3, 2.25.5, 2.24.4, 2.23.4, 2.22.5, 2.21.4, 2.20.5, 2.19.6, 2.18.5, 2.17.62.17.6. MEDIUM Mar 12, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-28153 An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.) MEDIUM Mar 12, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-35522 In LibTIFF, there is a memory malloc failure in tif_pixarlog.c. A crafted TIFF document can lead to an abort, resulting in a remote denial of service attack. MEDIUM Mar 12, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-27918 encoding/xml in Go before 1.15.9 and 1.16.x before 1.16.1 has an infinite loop if a custom TokenReader (for xml.NewTokenDecoder) returns EOF in the middle of an element. This can occur in the Decode, DecodeElement, or Skip method. MEDIUM Mar 11, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-27365 An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a Netlink message. MEDIUM Mar 7, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-27364 An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is adversely affected by the ability of an unprivileged user to craft Netlink messages. LOW Mar 7, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-27363 An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI subsystem, the transport\'s handle is available to unprivileged users via the sysfs file system, at /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the pointer to an iscsi_transport struct in the kernel module\'s global variables. LOW Mar 7, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-25639 A NULL pointer dereference flaw was found in the Linux kernel’s GPU Nouveau driver functionality in versions prior to 5.12-rc1 in the way the user calls ioctl DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC. This flaw allows a local user to crash the system. MEDIUM Mar 5, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-28038 An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931. MEDIUM Mar 5, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-25647 A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. HIGH Mar 3, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-27779 A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub\'s memory layout. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. MEDIUM Mar 3, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-14372 A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability. MEDIUM Mar 3, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-20225 A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. HIGH Mar 3, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-20233 A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. HIGH Mar 3, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-25632 A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. HIGH Mar 3, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-3418 grub2: GRUB 2.05 reintroduced CVE-2020-15705, grub fails to validate kernel signatures when booted directly without shim, allowing secure boot to be bypassed. (This issue did not affect grub as distributed in Ubuntu.) MEDIUM Mar 3, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-27749 A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. HIGH Mar 3, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-35524 Heap-based buffer overflow in TIFF2PDF tool in libtiff MEDIUM Mar 1, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2020-35523 Integer overflow in tif_getimage.c in libtiff MEDIUM Mar 1, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-27803 A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi Direct) provision discovery requests. It could result in denial of service or other impact (potentially execution of arbitrary code), for an attacker within radio range. MEDIUM Feb 27, 2021 10.19.45.16 (Wind River Linux LTS 19)
CVE-2021-27645 The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c. MEDIUM Feb 27, 2021 10.19.45.17 (Wind River Linux LTS 19)
CVE-2021-21309 Redis is an open-source, in-memory database that persists on disk. In affected versions of Redis an integer overflow bug in 32-bit Redis version 4.0 or newer could be exploited to corrupt the heap and potentially result with remote code execution. Redis 4.0 or newer uses a configurable limit for the maximum supported bulk input size. By default, it is 512MB which is a safe value for all platforms. If the limit is significantly increased, receiving a large request from a client may trigger several integer overflow scenarios, which would result with buffer overflow and heap corruption. We believe this could in certain conditions be exploited for remote code execution. By default, authenticated Redis users have access to all configuration parameters and can therefore use the “CONFIG SET proto-max-bulk-len” to change the safe default, making the system vulnerable. **This problem only affects 32-bit Redis (on a 32-bit system, or as a 32-bit executable running on a 64-bit system).** The problem is fixed in version 6.2, and the fix is back ported to 6.0.11 and 5.0.11. Make sure you use one of these versions if you are running 32-bit Redis. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent clients from directly executing `CONFIG SET`: Using Redis 6.0 or newer, ACL configuration can be used to block the command. Using older versions, the `rename-command` configuration directive can be used to rename the command to a random string unknown to users, rendering it inaccessible. Please note that this workaround may have an additional impact on users or operational systems that expect `CONFIG SET` to behave in certain ways. HIGH Feb 26, 2021 10.19.45.16 (Wind River Linux LTS 19)
CVE-2020-36254 scp.c in Dropbear before 2020.79 mishandles the filename of . or an empty filename, a related issue to CVE-2018-20685. MEDIUM Feb 25, 2021 10.19.45.16 (Wind River Linux LTS 19)
CVE-2020-35508 A flaw possibility of race condition and incorrect initialization of the process id was found in the Linux kernel child/parent process identification handling while filtering signal handlers. A local attacker is able to abuse this flaw to bypass checks to send any signal to a privileged process. MEDIUM Feb 24, 2021 10.19.45.16 (Wind River Linux LTS 19)
