RHBA-2012:0057 - mod_auth_kerb bug fix update

Synopsis

mod_auth_kerb bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

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.
