"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. (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. (CVE-2011-4110).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
