Russ Allbery uploaded new packages for openafs which fixed the following
security problems:
CVE-2011-0430 (DSA-2168-1)
Andrew Deason discovered that a double free in the Rx server process
could lead to denial of service or the execution of arbitrary code.
This affects the server components of the openafs package.
CVE-2011-0431 (DSA-2168-1)
It was discovered that insufficient error handling in the kernel module
could lead to denial of service. A local user can induce a kernel panic
in the OpenAFS client. This affects the kernel module component of the
openafs package.
Note that for the fix to CVE-2011-0431, you must rebuild the OpenAFS
kernel module and unload and reload the newly built kernel module after
upgrading openafs-modules-source or openafs-modules-dkms, whichever you
use.
For the lenny-backports distribution the problems have been fixed in
version 1.4.12.1+dfsg-4~bpo50+1.
For the oldstable distribution (lenny), this problem has been fixed in
version 1.4.7.dfsg1-6+lenny4.
For the stable distribution (squeeze), this problem has been fixed in
version 1.4.12.1+dfsg-4.
For the unstable distribution (sid), this problem has been fixed in
version 1.4.14+dfsg-1.
These problems were fixed upstream in the 1.4.14 release.
If you don't use pinning (see [1]) you have to update the package
manually via "apt-get -t lenny-backports install <packagelist>" with
the packagelist of your installed packages affected by this update.

We recommend to pin (in /etc/apt/preferences) the backports repository to
200 so that new versions of installed backports will be installed
automatically.
