Package        : mon
Vulnerability  : insecure temporary files
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2008-4477
Debian Bug     : 496398

Dmitry E. Oboukhov discovered that the test.alert script used in one of the 
alert functions in mon, a system to monitor hosts or services and alert 
about problems, creates temporary files insecurely, which may lead to a local 
denial of service through symlink attacks.

For the stable distribution (etch), this problem has been fixed in
version 0.99.2-9+etch2.

For the testing (lenny) and unstable distribution (sid), this problem has
been fixed in version 0.99.2-13.

We recommend that you upgrade your mon 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.
