First published: Wed Jan 11 2012(Updated: )

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. (CVE-2011-1162) Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. (CVE-2011-2203) 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.
