Package        : cvs
Vulnerability  : insecure temporary files
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2005-2693
Debian Bug     : 325106

Marcus Meissner discovered that the cvsbug program from gcvs, the
Graphical frontend for CVS, which serves the popular Concurrent
Versions System, uses temporary files in an insecure fashion.

For the old stable distribution (woody) this problem has been fixed in
version 1.0a7-2woody1.

For the stable distribution (sarge) this problem has been fixed in
version 1.0final-5sarge1.

The unstable distribution (sid) does not expose the cvsbug program.

We recommend that you upgrade your gcvs package.


Upgrade Instructions
- - --------------------

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.
