| MIT Kerberos 5 (aka krb5) 1.3.x, 1.4.x, 1.5.x, 1.6.x, 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 modify user-visible
prompt text, modify a response to a Key Distribution Center (KDC), or
forge a KRB-SAFE message via certain checksums that (1) are unkeyed or
(2) use RC4 keys.
