Package        : libapache-auth-ldap
Vulnerability  : format string
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2006-0150

"Seregorn" discovered a format string vulnerability in the logging
function of libapache-auth-ldap, an LDAP authentication module for the
Apache webserver, that can lead to the execution of arbitrary code.

For the old stable distribution (woody) this problem has been fixed in
version 1.6.0-3.1.

For the stable distribution (sarge) this problem has been fixed in
version 1.6.0-8.1

The unstable distribution (sid) does no longer contain libapache-auth-ldap.

We recommend that you upgrade your libapache-auth-ldap 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.
