Description

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).

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.
