Ubuntu 10.04 LTS : linux vulnerabilities (USN-1168-1)

Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

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
could exploit this to crash the system, leading to a denial of
service. (CVE-2011-3363).

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.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
CVSS Temporal Score : 6.8
(CVSS2#E:ND/RL:OF/RC:ND)
Public Exploit Available : false
