libcgroup - several

Several issues have been discovered in libcgroup, a library to control
and monitor control groups:

• CVE-2011-1006
  Heap-based buffer overflow by converting list of controllers for
  given task into an array of strings could lead to privilege
  escalation by a local attacker.
• CVE-2011-1022
  libcgroup did not properly check the origin of Netlink messages,
  allowing a local attacker to send crafted Netlink messages which
  could lead to privilege escalation.

The oldstable distribution (lenny) does not contain libcgroup packages.

For the stable distribution (squeeze), this problem has been fixed in
version 0.36.2-3+squeeze1.

For the testing distribution (wheezy) and unstable distribution (sid),
this problem will be fixed soon.

We recommend that you upgrade your libcgroup packages.
