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

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.

Buffer overflow in libtelnet/encrypt.c in telnetd in FreeBSD 7.3
through 9.0, MIT Kerberos Version 5 Applications (aka krb5-appl)
