Package        : libpam-heimdal
Vulnerability  : programming error
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2009-0361

Derek Chan discovered that the PAM module for the Heimdal Kerberos
implementation allows reinitialisation of user credentials when run
from a setuid context, resulting in potential local denial of service
by overwriting the credential cache file or to local privilege
escalation.

For the stable distribution (etch), this problem has been fixed in
version 2.5-1etch1.

For the upcoming stable distribution (lenny), this problem has been
fixed in version 3.10-2.1.

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

We recommend that you upgrade your libpam-heimdal package.

- --------------------

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

You may use an automated update by adding the resources from the
footer to the proper configuration.
