Secunia

A security issue has been reported in Novell Access Manager Identity Server, which can be exploited by malicious, local users to bypass certain security restrictions.

The security issue is caused due to the server improperly terminating a session established by using an X509 certificate. This can be exploited to gain access to the session via the same browser instance.

Successful exploitation requires that X509 authentication is enabled and that the attacker has access to the victim's browser instance.

The security issue is reported in Novell Access Manager version 3 Support Pack 4. Other versions may also be affected.

Solution
Close the browser after logging out. Please see the vendor's advisory for additional workaround information.
