MIT Kerberos 5 (aka krb5) 1.7.x and 1.8.x through 1.8.3 does not
properly determine the acceptability of checksums, which might allow
remote attackers to forge GSS tokens, gain privileges, or have
unspecified other impact via (1) an unkeyed checksum, (2) an unkeyed
PAC checksum, or (3) a KrbFastArmoredReq checksum based on an RC4 key.";
