"Updated mod_auth_any packages are available for Red Hat Enterprise
Linux. These updated packages fix vulnerabilities associated with the
manner in which mod_auth_any escapes shell arguments when calling
external programs.

The Web server module mod_auth_any allows the Apache httpd server to
call arbitrary external programs to verify user passwords.

Vulnerabilities have been found in versions of mod_auth_any included
in Red Hat Enterprise Linux concerning the method by which
mod_auth_any escapes shell arguments when calling external programs.
These vulnerabilities allow remote attackers to run arbitrary commands
as the user under which the Web server is running. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2003-0084 to these issues.

All users are advised to upgrade to these errata packages, which
change the method by which external programs are invoked and,
therefore, make these programs invulnerable to these issues.

Red Hat would like to thank Daniel Jarboe and Maneesh Sahani for
bringing these issues to our attention."
