Debian Security Advisory DSA 116-1                     security () debian org

Package        : cfs
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no

Zorgon found several buffer overflows in cfsd, a daemon that pushes
encryption services into the Unix(tm) file system.  We are not yet
sure if these overflows can successfully be exploited to gain root
access to the machine running the CFS daemon.  However, since cfsd can
easily be forced to die, a malicious user can easily perform a denial
of service attack to it.

This problem has been fixed in version 1.3.3-8.1 for the stable Debian
distribution and in version 1.4.1-5 for the testing and undtable
distribution of Debian.

We recommend that you upgrade your cfs package 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.
