Ubuntu 16.04 LTS : linux-snapdragon vulnerability (USN-3128-3)
Medium Nessus Plugin ID 94735
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionOndrej Kozina discovered that the keyring interface in the Linux kernel contained a buffer overflow when displaying timeout events via the /proc/keys interface. 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-4.4-snapdragon and / or linux-image-snapdragon packages.
