"Andy Lutomirski discover an error in the Linux kernel's credential
handling on unix sockets. A local user could exploit this flaw to gain
administrative privileges. (CVE-2013-1979)

A buffer overflow vulnerability was discovered in the Broadcom tg3
ethernet driver for the Linux kernel. A local user could exploit this
flaw to cause a denial of service (crash the system) or potentially
escalate privileges on the system. (CVE-2013-1929)

A flaw was discovered in the Linux kernel's ftrace subsystem
interface. A local user could exploit this flaw to cause a denial of
service (system crash). (CVE-2013-3301).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
