Ubuntu 16.10 : linux-raspi2 vulnerabilities (USN-3152-2)

high Nessus Plugin ID 95574

Language:

Synopsis

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

Description

Philip Pettersson discovered a race condition in the af_packet implementation in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service (system crash) or run 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.

Solution

Update the affected linux-image-4.8-raspi2 and / or linux-image-raspi2 packages.
