3. Problem description:

The mod_auth_pgsql package is an httpd module that allows user authentication against information stored in a PostgreSQL database.

Several format string flaws were found in the way mod_auth_pgsql logs information. It may be possible for a remote attacker to execute arbitrary code as the 'apache' user if mod_auth_pgsql is used for user authentication. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-3656 to this issue.

Please note that this issue only affects servers which have mod_auth_pgsql installed and configured to perform user authentication against a PostgreSQL database.

All users of mod_auth_pgsql should upgrade to these updated packages, which contain a backported patch to resolve this issue.

This issue does not affect the mod_auth_pgsql package supplied with Red Hat Enterprise Linux 2.1.

Red Hat would like to thank iDefense for reporting this issue.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command:
