Ubuntu 14.10 : linux vulnerability (USN-2600-1)

Medium Nessus Plugin ID 83261


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


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.


Update the affected linux-image-3.16-generic, linux-image-3.16-generic-lpae and / or linux-image-3.16-lowlatency packages.
