Package        : cvs
Vulnerability  : improper variable initialization
Problem-Type   : remote
Debian-specific: no

Kim Nielsen recently found an internal problem with the CVS server and
reported it to the vuln-dev mailing list.  The problem is triggered by
an improperly initialized global variable.  A user exploiting this can
crash the CVS server, which may be accessed through the pserver
service and running under a remote user id.  It is not yet clear if
the remote account can be exposed, through.

This problem has been fixed in version 1.10.7-9 for the stable Debian
distribution and in version newer than 1.11.1p1debian-3 for the
testing and unstable distribution of Debian (not yet uploaded,
though).

We recommend that you upgrade your CVS package.

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.
