3. 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.
