Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

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)

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.
