(RHSA-2003:114) mod_auth_any security update

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 CAN-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.
