Ubuntu Security Notice 3018-1 - Jesse Hertz and Tim Newsham discovered that the Linux netfilter implementation did not correctly perform validation when handling 32 bit compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local unprivileged attacker could use this to cause a denial of service (system crash) or execute arbitrary code with administrative privileges. Kangjie Lu discovered an information leak in the core USB implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. Various other issues were also addressed.
