"Updated mod_auth_pgsql packages that fix format string security issues
are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having critical security impact by the
Red Hat Security Response Team.

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."
