Debian Security Advisory DSA 233-1                     security@debian.org

Package        : cvs
Vulnerability  : doubly freed memory
Problem-Type   : remote
Debian-specific: no
CVE Id         : CAN-2003-0015

Stefan Esser discovered a problem in cvs, a concurrent versions
system, which is used for many Free Software projects.  The current
version contais a flaw that can be used by a remote attacker to
execute arbitrary code on the CVS server under the user id the CVS
server runs as.  Anonymous read-only access is sufficient to exploit
this problem.

For the stable distribution (woody) this problem has been
fixed in version 1.11.1p1debian-8.1.

For the old stable distribution (potato) this problem has been fixed
in version 1.10.7-9.2.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your cvs package immediately.


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.
