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)

An information leak was discovered in the Linux kernel's tkill and tgkill
system calls when used from compat processes. A local user could exploit
this flaw to examine potentially sensitive kernel memory. (CVE-2013-2141)
