Synopsis

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

Description

(CVE-2013-4254)

A failure to validate block numbers was discovered in the Linux kernel's implementation of the XFS filesystem. A local user can cause a denial of service (system crash) if they can mount, or cause to be mounted a corrupted or special crafted XFS filesystem. (CVE-2013-1819)

An information leak was discovered in the Linux kernel's IPSec key_socket when using the notify_policy interface. A local user could exploit this flaw to examine potentially sensitive information in kernel memory. (CVE-2013-2237).

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-3.5-generic and / or linux-image-3.5-highbank packages.
