USN-1275-1: Linux kernel vulnerability

First published: Mon Nov 21 2011(Updated: )

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.
