USN-3311-1 fixed a vulnerability in libnl. This update provides the corresponding update for Ubuntu 12.04 ESM.
It was discovered that libnl incorrectly handled memory when performing certain operations. A local attacker could possibly use this issue to cause libnl to crash, resulting in a denial of service, or execute arbitrary code.
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.
