| Description: | Description:
The remote host is missing an update to linux-image-2.6.35-30-generic
announced via advisory USN-1242-1.
Details:
It was discovered that the security fix for CVE-2010-4250 introduced a
regression. A remote attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2011-1479)
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)
Vasiliy Kulikov discovered that /proc/PID/io did not enforce access
restrictions. A local attacker could exploit this to read certain
information, leading to a loss of privacy. (CVE-2011-2495)
It was discovered that the EXT4 filesystem contained multiple off-by-one
flaws. A local attacker could exploit this to crash the system, leading to
a denial of service. (CVE-2011-2695)
Christian Ohm discovered that the perf command looks for configuration
files in the current directory. If a privileged user were tricked into
running perf in a directory containing a malicious configuration file, an
attacker could run arbitrary commands and possibly gain privileges.
(CVE-2011-2905)
Vasiliy Kulikov discovered that the Comedi driver did not correctly clear
memory. A local attacker could exploit this to read kernel stack memory,
leading to a loss of privacy. (CVE-2011-2909)
Dan Kaminsky discovered that the kernel incorrectly handled random sequence
number generation. An attacker could use this flaw to possibly predict
sequence numbers and inject packets. (CVE-2011-3188)
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)
