Summary
Red Hat Security Advisory: mod_auth_any security update

Notes

Topic
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.
Details
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.
