CVEs (cve.mitre.org): CVE-2005-3656

Details

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.
