"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)

Dan Rosenberg reported an error in the old ABI compatibility layer of
ARM kernels. A local attacker could exploit this flaw to cause a
denial of service or gain root privileges. (CVE-2011-1759)

Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
partitions. A local user could exploit this to cause a denial of
service or escalate privileges. (CVE-2011-2182)

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 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."
