mod_auth_mellon provides a SAML 2.0 authentication module for the Apache HTTP Server.

An information disclosure flaw was found in mod_auth_mellon's session handling that could lead to sessions overlapping in memory. A remote attacker could potentially use this flaw to obtain data from another user's session. (CVE-2014-8566)

It was found that uninitialized data could be read when processing a user's logout request. By attempting to log out, a user could possibly cause the Apache HTTP Server to crash. (CVE-2014-8567)

Red Hat would like to thank the mod_auth_mellon team for reporting these issues. Upstream acknowledges Matthew Slowe as the original reporter of CVE-2014-8566.
