Buffer overflow in libtelnet/encrypt.c in telnetd in FreeBSD 7.3 through 9.0, MIT Kerberos Version 5 Applications aka krb5-appl 1.0.2 and earlier, Heimdal 1.5.1 and earlier, GNU inetutils, and possibly other products allows remote attackers to execute arbitrary code via a long encryption key, as...

telnet-encryption NSE Script

Determines whether the encryption option is supported on a remote telnet server. Some systems including FreeBSD and the krb5 telnetd available in many Linux distributions implement this option incorrectly, leading to a remote root vulnerability. This script currently only tests whether encryption...
