APP: MIT Kerberos KDC Authentication Denial of Service
This signature detects attempts to exploit a known denial of service vulnerability in MIT's Kerberos KDC. It is due to an assertion failure when handling invalid Authentication Service requests. Remote unauthenticated attackers can exploit this by sending a crafted AS-REQ packet to the target KDC, causing it to crash, creating a denial-of-service condition.
Extended Description
MIT Kerberos is prone to a remote denial-of-service vulnerability. An attacker may exploit this issue to crash the KDC service, resulting in a denial-of-service condition. MIT Kerberos 5 1.7 and 1.7.1 are vulnerable.
