MIT Kerberos 5 (krb5) through 1.22.2 contains a NULL pointer dereference in make cred list() in rd cred.c that allows authenticated Kerberos clients to crash services by sending mismatched KRB-CRED arrays. Attackers can send forwarded credentials with more tickets than ticket info entries through gss accept sec context() to crash GSS-API acceptor services, causing denial of service.
