LIN1021-6060 : Security Advisory - qemu - CVE-2023-1386

Created: Jul 19, 2023 Updated: Jul 25, 2023

Found In Version: 10.21.20.1

Severity: Standard

Applicable for: Wind River Linux LTS 21

Component/s: Userspace

Description

A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. When a local user in the guest writes an executable file with SUID or SGID, none of these privileged bits are correctly dropped. As a result, in rare circumstances, this flaw could be used by malicious users in the guest to elevate their privileges within the guest and help a host local user to elevate privileges on the host.
