First published: Fri May 24 2013(Updated: )
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) 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) 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)
