The ASN.1 decoder library in the MIT Kerberos 5 distribution is
vulnerable to a denial-of-service attack causing an infinite loop in
the decoder. The KDC is vulnerable to this attack.

An unauthenticated remote attacker can cause a KDC or application
server to hang inside an infinite loop.

An attacker impersonating a legitimate KDC or application server may
cause a client program to hang inside an infinite loop.
