MDKSA-2003:081: postfix Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the postfix package

Detailed Explanation for this Vulnerability Test

The remote host is missing the patch for the advisory MDKSA-2003:081 (postfix).

Two vulnerabilities were discovered in the postfix MTA by Michal Zalewski.
Versions prior to 1.1.12 would allow a possible hacker to bounce- scan private
networks or use the daemon as a DDoS (Distributed Denial of Service) tool by
forcing the daemon to connect to an arbitrary service at an arbitrary IP address
and receiving either a bounce message or by timing. As well, versions prior to
1.1.12 have a bug where a malformed envelope address can cause the queue manager
to lock up until an entry is removed from the queue and also lock up the SMTP
listener leading to a DoS.
Postfix version 1.1.13 corrects these issues. The provided packages have been
patched to fix the vulnerabilities.
