Package        : libapache2-mod-auth-pgsql
Vulnerability  : format string vulnerability
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2005-3656
Debian Bug     : 307852

iDEFENSE reports that a format string vulnerability in mod_auth_pgsql, a
library used to authenticate web users against a PostgreSQL database,
could be used to execute arbitrary code with the privileges of the httpd
user.

The old stable distribution (woody) does not contain
libapache2-mod-auth-pgsql.

For the stable distribution (sarge) this problem has been fixed in
version 2.0.2b1-5sarge0.

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

We recommend that you upgrade your libapache2-mod-auth-pgsql 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
