- From advisory:

"Attackers may remotely exploit this vulnerability to gain "root" or 
superuser control of any vulnerable Sendmail server. Sendmail and all 
other email servers are typically exposed to the Internet in order to 
send and receive Internet email. Vulnerable Sendmail servers will not be 
protected by legacy security devices such as firewalls and/or packet 
filters. This vulnerability is especially dangerous because the exploit 
can be delivered within an email message and the attacker doesn't need 
any specific knowledge of the target to launch a successful attack."
