  script_tag(name:"insight", value:"Vasiliy Kulikov discovered that kvm did not correctly clear memory. A local
attacker could exploit this to read portions of the kernel stack, leading
to a loss of privacy. (CVE-2010-3881)

Timo Warns discovered that the LDM disk partition handling code did not
correctly handle certain values. By inserting a specially crafted disk
device, a local attacker could exploit this to gain root privileges.
(CVE-2011-1017)

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)

Dan Rosenberg discovered that MPT devices did not correctly validate
certain values in ioctl calls. If these drivers were loaded, a local
attacker could exploit this to read arbitrary kernel memory, leading to a
loss of privacy. (CVE-2011-1494, CVE-2011-1495)

Tavis Ormandy discovered that the pidmap function did not correctly handle
large requests. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2011-1593)

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, CVE-2011-1748)

Vasiliy Kulikov discovered that the AGP driver did not check certain ioctl
values. A local attacker with access to the video subsystem could exploit
this to crash the system, leading to a denial of service, or possibly gain
root privileges. (CVE-2011-1745, CVE-2011-2022)

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)

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)

Dan Rosenberg discovered that the DCCP stack did not correctly handle
certain packet structures. A remote attacker could exploit this to crash
the system, leading to a denial of service. (CVE-2011-1770)

Timo Warns discovered that the EFI GUID partition table was not correctly
parsed. A physically local attacker that could insert mountable devices
could exploit this to crash the system or possibly gain root privileges.
(CVE-2011-1776)

Yogesh Sharma discovered that CIFS did not correctly handle UNCs that had
no prefixpaths. A local attacker with access to a CIFS partition ... [Please see the references for more information on the vulnerabilities]");
