I'm not an expert, but I was running test with OpenVAS (nessus equivalent in
opensource) to test my server and here what he said under jabber-server
(5269/tcp) :
Reported by NVT "Generic format string" (

The remote service is vulnerable to a format string attack
An attacker may use this flaw to execute arbitrary code on this host.

Solution : upgrade your software or contact your vendor and inform it of
See also : http://www.securityfocus.com/archive/1/81565
Risk factor : High

Of course it seems to be a generic routine as he didn't identified ejabberd,
and of the course the link it give seems dead....
As the report is quite scary : execute arbitrary code, risk high ; I would
like to know if the flaw is confirmed, false positive, or unsure.
(If it's a false positive, It might be a good idea to warn OpenVAS people
about this with hope they can correct that).
