Ubuntu 10.04 LTS : linux-lts-backport-natty vulnerabilities (USN-1386-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

The linux kernel did not properly account for PTE pages when deciding
which task to kill in out of memory conditions. A local, unprivileged
could exploit this flaw to cause a denial of service. (CVE-2011-2498)

A flaw was discovered in the TOMOYO LSM's handling of mount system
calls. An unprivileged user could oops the system causing a denial of
service. (CVE-2011-2518)

Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local
user who can mount a FUSE file system could cause a denial of service.
(CVE-2011-3353)

A bug was discovered in the Linux kernel's calculation of OOM (Out of
memory) scores, that would result in the wrong process being killed. A
user could use this to kill the process with the highest OOM score,
even if that process belongs to another user or the system.
(CVE-2011-4097)

A flaw was found in KVM's Programmable Interval Timer (PIT). When a
virtual interrupt control is not available a local user could use this
to cause a denial of service by starting a timer. (CVE-2011-4622)

A flaw was discovered in the XFS filesystem. If a local user mounts a
specially crafted XFS image it could potential execute arbitrary code
on the system. (CVE-2012-0038)

Chen Haogang discovered an integer overflow that could result in
memory corruption. A local unprivileged user could use this to crash
the system. (CVE-2012-0044)

A flaw was found in the linux kernels IPv4 IGMP query processing. A
remote attacker could exploit this to cause a denial of service.
(CVE-2012-0207).

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.

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:C)
CVSS Temporal Score : 6.1
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
