Pardus Linux Security Advisory 2008-40            security () pardus org tr
       Date: 2008-09-06
   Severity: 1
       Type: Local


A security issue has been reported in Postfix, which can be exploited by
malicious, local users to cause a DoS (Denial of Service).


The security issue is caused due to  Postfix  leaking  the  epoll  file
descriptor when executing non-Postfix commands, which can be  exploited
to cause a DoS.

The security issue only affects Postfix 2.4 or later in combination with
epoll (e.g. Linux 2.6).

Affected packages:

   Pardus 2008:
     postfix, all before 2.5.4-21-5


There are update(s) for postfix. You can update them via Package Manager
or with a single command from console:

     pisi up postfix
