- 公告与补丁

        Zone Labs, as of April 25 2000 is offering a Beta to correct this problem:
        http://www.zonelabs.com/beta_download.htm
        Zone Labs Support issued the following statement to the Bugtraq mailing list on 12 May 2000.
        This is the company position on the Port 67 issue....
        The port 67 vulnerability has been eliminated. The upgraded version of ZoneAlarm contains the fix and is available from
        http://www.zonelabs.com/download_ZA.htm
        Previously, ZoneAlarm did not prevent TCP or UDP packets from entering the computer through port 67. Port 67 was deliberately left open to avoid instabilities encountered on Windows NT machines using DHCP.
        We felt confident that this did not compromise your security or the security of our other users. ZoneAlarm, in addition to its firewall capabilities, provides protection against hackers through its unique application control feature. Our product only allows applications the user specifically approves to communicate via the Internet. Even if a port appears to be open for traffic from the outside, it is in fact closed to all unauthorized traffic. Therefore port 67 could not (and cannot) be co-opted unknowingly into communicating your private information to a hacker via a Trojan horse. Our two measures of security taken together provide the utmost protection for our users.
        Best regards Zone Labs Support

Certain versions of Zone Labs personal Firewall have a vulnerability which allows malicious users to port scan the firewall without being detected. In particular if the port scan originates from source port 67 on the attacking host the ZoneAlarm fails to register the attack.

ZoneAlarm contains a flaw that may allow a remote attacker to bypass the ruleset. The issue is due to ZoneAlarm not monitoring and alerting UDP traffic with a source port of 67. This allows an attacker to bypass the firewall to reach protected hosts without setting off warnings on the firewall.
