Ubuntu Security Notice 1323-1 - Peter Huewe discovered an information leak in the handling of reading security-related TPM data. A local, unprivileged user could read the results of a previous TPM command. Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. A flaw was found in the b43 driver in the Linux kernel. An attacker could use this flaw to cause a denial of service if the system has an active wireless interface using the b43 driver. Various other issues were also addressed.
