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. 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. 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. All users of mod_auth_mellon are advised to upgrade to this updated package, which contains a backported patch to correct these issues.
