Ubuntu 16.10 : linux vulnerability (USN-3129-1)

medium Nessus Plugin ID 94736

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Ondrej 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.

Solution

Update the affected packages.
