Package : cfengine2
Vulnerability : insecure temporary files
Problem type : local
Debian-specific: no
CVE ID : CAN-2005-2960

Javier Fernández-Sanguino Peña discovered insecure temporary file use
in cfengine2, a tool for configuring and maintaining networked
machines, that can be exploited by a symlink attack to overwrite
arbitrary files owned by the user executing cfengine, which is
probably root.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) these problems have been fixed in
version 2.1.14-1sarge1.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your cfengine2 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 3.1 alias sarge
