| Description: | Description:
The remote host is missing an update to linux-image-3.0.0-13-generic
announced via advisory USN-1294-1.
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)
Nick Bowler discovered the kernel GHASH message digest algorithm
incorrectly handled error conditions. A local attacker could exploit this
to cause a kernel oops. (CVE-2011-4081)
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)
