Ubuntu 12.04 LTS : linux-lts-trusty vulnerability (USN-3250-2)

High Nessus Plugin ID 99099


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


USN-3250-1 fixed a vulnerability in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 LTS.

It was discovered that the xfrm framework for transforming packets in the Linux kernel did not properly validate data received from user space. A local attacker could use this to cause a denial of service (system crash) or execute 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.


Update the affected packages.
