DSA 137-1-mm

by Nikola Strahija on July 30th, 2002 Marcus Meissner and Sebastian Krahmer discovered and fixed a temporary file vulnerability in the mm shared memory library. This problem can be exploited to gain root access to a machine running Apache which is linked against this library, if shell access to the user ``www-data'' is already available (which could easily be triggered through PHP).

This problem has been fixed in the upstream version 1.2.0 of mm, which
will be uploaded to the unstable Debian distribution while this
advisory is released. Fixed packages for potato (Debian 2.2) and
woody (Debian 3.0) are linked below.

We recommend that you upgrade your libmm packages immediately.

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
