The problem can be corrected by upgrading your system to the following package versions: Ubuntu 7.10: postfix 2.4.5-3ubuntu1.3 Ubuntu 8.04 LTS: postfix 2.5.1-2ubuntu1.2 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Wietse Venema discovered that Postfix leaked internal file descriptors when executing non-Postfix commands. A local attacker could exploit this to cause Postfix to run out of descriptors, leading to a denial of service.
