Previous ID: LIN3-28901
Found In Version: 6.0
Fix Version: 6.0.0.3
Severity: Severe
Applicable for: Wind River Linux 6
Component/s: Kernel
The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c.
