Description

krb5 vulnerability

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.

non-EAP authentication methods for communications between Kerberos and a

RADIUS server.
