"Dan Rosenberg discovered that multiple terminal ioctls did not
correctly initialize structure memory. A local attacker could exploit
this to read portions of kernel stack memory, leading to a loss of
privacy. (CVE-2010-4076, CVE-2010-4077)

Neil Horman discovered that NFSv4 did not correctly handle certain
orders of operation with ACL data. A remote attacker with access to an
NFSv4 mount could exploit this to crash the system, leading to a
denial of service. (CVE-2011-1090)

Timo Warns discovered that OSF partition parsing routines did not
correctly clear memory. A local attacker with physical access could
plug in a specially crafted block device to read kernel memory,
leading to a loss of privacy. (CVE-2011-1163)

Timo Warns discovered that the GUID partition parsing routines did not
correctly validate certain structures. A local attacker with physical
access could plug in a specially crafted block device to crash the
system, leading to a denial of service. (CVE-2011-1577)

Oliver Hartkopp and Dave Jones discovered that the CAN network driver
did not correctly validate certain socket structures. If this driver
was loaded, a local attacker could crash the system, leading to a
denial of service. (CVE-2011-1598)

Vasiliy Kulikov discovered that the AGP driver did not check the size
of certain memory allocations. A local attacker with access to the
video subsystem could exploit this to run the system out of memory,
leading to a denial of service. (CVE-2011-1746).

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."
