A local vulnerability has been discovered in drbd8. Philipp Reisner fixed an issue in the drbd kernel module that allows local users to send netlink packets to perform actions that should be restricted to users with CAP_SYS_ADMIN privileges. This is a similar issue to those described by CVE-2009-3725. This update also fixes an ABI compatibility issue which was introduced by linux-2.6 . The prebuilt drbd module packages listed in this advisory require a linux-image package version 2.6.26-21lenny3 or greater.
