USN-1294-1: Linux kernel (Oneiric backport) vulnerabilities

08 December 2011

Several security issues were fixed in the kernel.

Releases

Packages

  • linux-lts-backport-oneiric - Linux kernel backport from Oneiric

Details

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)

Vasiliy Kulikov discovered that taskstats did not enforce access
restrictions. A local attacker could exploit this to read certain
information, leading to a loss of privacy. (CVE-2011-2494)

Qianfeng Zhang discovered that the bridge networking interface incorrectly
handled certain network packets. A remote attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-2942)

Yasuaki Ishimatsu discovered a flaw in the kernel's clock implementation. A
local unprivileged attacker could exploit this causing a denial of service.
(CVE-2011-3209)

Zheng Liu discovered a flaw in how the ext4 filesystem splits extents. A
local unprivileged attacker could exploit this to crash the system, leading
to a denial of service. (CVE-2011-3638)

Scot Doyle discovered that the bridge networking interface incorrectly
handled certain network packets. A remote attacker could exploit this to
crash the system, leading to a denial of service. (CVE-2011-4087)

A bug was found in the way headroom check was performed in
udp6_ufo_fragment() function. A remote attacker could use this flaw to
crash the system. (CVE-2011-4326)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.04

After a standard system update you need to reboot your computer to make
all the necessary changes.
