MandrakeSoft Security Advisory MDKSA-2003:081 : postfix

 

August 4th, 2003

Updated postfix packages fix remote DoS

 

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.

 

 

The released versions of Mandrake GNU/Linux affected are:

• 8.2

 

[*] 9.0

 

[*] Multi Network Firewall 8.2

 

[*] Corporate Server 2.1
