Philipp Reisner reported an issue in the connector subsystem which allows unprivileged users to send netlink packets. This allows local users to manipulate settings for uvesafb devices which are normally reserved for privileged users.
Jermome Marchand reported an issue in the futex subsystem that allows a local user to force an invalid futex state which results in a denial of service (oops).
This update also includes fixes for regressions introduced by previous updates. See the referenced Debian bug pages for details.
For the stable distribution (lenny), this problem has been fixed in version 2.6.26-21lenny4.
We recommend that you upgrade your linux-2.6 and user-mode-linux packages.
The following matrix lists additional source packages that were rebuilt for compatibility with or to take advantage of this update:

|Title:||The wake_futex_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 does not properly handle certain unlock operations for a Priority Inheritance (PI) futex, which allows local users to cause a denial of service (OOPS) and possibly have unspecified other impact via vectors involving modification of the futex value from user space.|
