Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

Description

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.

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