Summary
krb5 vulnerability
Details

Goldberg, Miro Haller, Nadia Heninger, Mike Milano, Dan Shumow, Marc Stevens, and Adam Suhl discovered that Kerberos incorrectly authenticated certain responses. An attacker able to intercept communications between a RADIUS client and server could possibly use this issue to forge responses, bypass authentication, and access network devices and services.

This update introduces support for the Message-Authenticator attribute in non-EAP authentication methods for communications between Kerberos and a RADIUS server.
