Kerberos telnet Crafted Username Remote Authentication Bypass
An authentication bypass vulnerability exists in the MIT krb5 telnet daemon due to a failure to sanitize malformed usernames. This allows usernames beginning with '-e' to be interpreted as a command-line flag by the login.krb5 program. A remote attacker can exploit this, via a crafted username, t...
