Ubuntu 12.04 LTS : linux-lts-trusty vulnerability (USN-2870-2)
High Nessus Plugin ID 88011
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionYevgeny Pats discovered that the session keyring implementation in the Linux kernel did not properly reference count when joining an existing session keyring. A local attacker could use this to cause a denial of service (system crash) or possibly execute 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.
SolutionUpdate the affected linux-image-3.13-generic and / or linux-image-3.13-generic-lpae packages.
