Ubuntu 12.04 LTS : linux-lts-trusty vulnerability (USN-3149-2)

Description

USN-3149-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 LTS. Philip Pettersson discovered a race condition in the af_packet implementation in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service (system crash) or run arbitrary code with administrative privileges. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
