                    Mandrake Linux Security Update Advisory
    ________________________________________________________________________

    Package name: postfix
    Advisory ID: MDKSA-2003:081
    Date: August 4th, 2003

    Affected versions: 8.2, 9.0, Corporate Server 2.1,
                            Multi Network Firewall 8.2
    ________________________________________________________________________

    Problem Description:

     Two vulnerabilities were discovered in the postfix MTA by Michal
     Zalewski. Versions prior to 1.1.12 would allow an attacker 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.
