Ubuntu 12.04 LTS : linux-lts-trusty vulnerability (USN-3034-2)
Medium Nessus Plugin ID 92314
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-3034-1 fixed a vulnerability 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.
Jan Stancek discovered that the Linux kernel's memory manager did not properly handle moving pages mapped by the asynchronous I/O (AIO) ring buffer to the other nodes. A local attacker could use this to cause a denial of service (system crash).
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.
SolutionUpdate the affected linux-image-3.13-generic and / or linux-image-3.13-generic-lpae packages.
