Debian Bernhard R. Link discovered that the CVS browsing interface of Gforge, a collaborative development tool, performs insufficient escaping of URLs, which allows the execution of arbitrary shell commands with the privileges of the www-data user.

Package        : gforge-plugin-scmcvs
Vulnerability  : missing input sanitising
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2007-0246

Bernhard R. Link discovered that the CVS browsing interface of Gforge, a
collaborative development tool, performs insufficient escaping of URLs,
which allows the execution of arbitrary shell commands with the privileges
of the www-data user.

The oldstable distribution (sarge) is not affected by this problem.

For the stable distribution (etch) this problem has been fixed in
version 4.5.14-5.

For the unstable distribution (sid) this problem has been fixed in
version 4.5.14-6.

We recommend that you upgrade your gforge-plugin-scmcvs 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.


Debian GNU/Linux 4.0 alias etch

  its next update.
