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. (CVE-2011-3359)
A flaw was found in how the Linux kernel handles user-defined key types. An
unprivileged local user could exploit this to crash the system.
