U radu programskog paketa libcgroup uočene su dvije sigurnosne nepravilnosti. Riječ je o programskoj biblioteci namijenjenoj kontroli i praćenju rada kontrolnih grupa. Jedna od nepravilnosti je uzrokovana pojavom prepisivanja spremnika gomile prilikom konverzije između različitih tipova podataka. Druga ranjivost je posljedica nepravilne provjere pošiljaoca Netlink poruke. Uslijed zloupotrebe napadač može povećati prava na ranjivom sustavu slanjem posebno obrađene Netlink poruke. Svim korisnicima ranjivog paketa savjetuje se instalacija dostupne programske nadogradnje.

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:

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.

We recommend that you upgrade your libcgroup packages.
