Bug Fix Advisory mod_auth_kerb bug fix update

Advisory: RHBA-2012:0057-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2012-01-24
Last updated on: 2012-01-24
Affected Products: RHEL Desktop Workstation (v. 5 client)
Red Hat Enterprise Linux (v. 5 server)

Details

An updated mod_auth_kerb package that fixes one bug is now available for Red Hat
Enterprise Linux 5.

The mod_auth_kerb package provides a module for the Apache HTTP Server designed
to provide Kerberos authentication over HTTP. The module supports the Negotiate
authentication method, which performs full Kerberos authentication based on
ticket exchanges.

This update fixes the following bug:

* The mod_auth_kerb module did not use the Kerberos libraries in a thread-safe
way. Therefore, if mod_auth_kerb ran under a multi-threaded Apache HTTP Server,
authentication requests could terminate unexpectedly with a segmentation fault.
With this update, the thread-safety problem has been fixed, and thread crashes
no longer occur under these circumstances. (BZ#783228)

All users of mod_auth_kerb are advised to upgrade to this updated package, which
fixes this bug.
