Ubuntu 12.04 LTS : linux vulnerability (USN-2526-1)
Medium Nessus Plugin ID 81772
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that the Linux kernel's Infiniband subsystem did not properly sanitize its input parameters while registering memory regions from userspace. A local user could exploit this flaw to cause a denial of service (system crash) or to potentially gain 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 packages.
