Summary
The remote host is missing an update to libcgroup announced via advisory DSA 2193-1.
Insight
Insight
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 libgroup 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.
Solution
Solution
We recommend that you upgrade your libcgroup packages.
