Hello,
I have released this PoC for the Linux-only local denial of service
caused by the leak of epoll file descriptors.
This Proof of concept creates a pipe and adds it in postfix's epoll file
descriptor.
When the pipe is added, an endless loop will launch lots of events to
the local and master postfix processes.=20
This PoC will slowdown the system a lot.
You can find all the needed files at
http://www.wekk.net/research/CVE-2008-4042/ and
http://www.wekk.net/research/CVE-2008-3889/ and attached with this
email.
Feel free to write me for feedback, corrections, etc.
