SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionDmitry Vyukov discovered that the Linux kernel's keyring handler attempted to garbage collect incompletely instantiated keys. A local unprivileged 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-3.16-generic, linux-image-3.16-generic-lpae and / or linux-image-3.16-lowlatency packages.
