Ubuntu 11.10 : linux vulnerability (USN-1275-1)

medium Nessus Plugin ID 56917

Synopsis

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

Description

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)

Mathieu Desnoyers discovered that the kernel sockets implementation incorrectly dereferenced user pointers. A local attacker could possibly exploit this to crash the system. (CVE-2011-4594).

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
