Debian Security Advisory DSA-2193-1 email@example.com http://www.debian.org/security/ Thijs Kinkhorst March 16, 2011 http://www.debian.org/security/faq
Package : libcgroup Vulnerability : several Problem type : local Debian-specific: no CVE ID : CVE-2011-1006 CVE-2011-1022 Debian Bug : 615987
Several issues have been discovered in libcgroup, a library to control and monitor control groups:
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.
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.
We recommend that you upgrade your libcgroup packages.
