Description Jan Lieskovsky 2011-02-25 13:27:36 UTC
It was discovered that libcgroup did not properly check
the origin of Netlink messages. A local attacker could
use this flaw to send crafted Netlink messages to the
cgrulesengd daemon, causing it to put processes into one
or more existing control groups, based on the attacker's
choosing, possibly allowing the particular tasks to run
with more resources (memory, CPU, etc.) than originally
