Ubuntu 12.04 LTS : linux-lts-trusty vulnerability (USN-2597-2)

medium Nessus Plugin ID 83331

Language:

Synopsis

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

Description

USN-2597-1 fixed vulnerabilities in the Linux kernel, however an unrelated regression in the auditing of some path names was introduced. Due to the regression the system could crash under certain conditions.

This update fixes the problem.

We apologize for the inconvenience.

A race condition between chown() and execve() was discovered in the Linux kernel. A local attacker could exploit this race by using chown on a setuid-user-binary to 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.

Solution

Update the affected linux-image-3.13-generic and / or linux-image-3.13-generic-lpae packages.
