CRITICAL:
Moderately critical

IMPACT:
DoS

WHERE:
>From remote

SOFTWARE:
Zoidcom 0.x
http://secunia.com/product/15305/

DESCRIPTION:
Luigi Auriemma has discovered a vulnerability in Zoidcom, which can
be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to the incorrect processing of
malformed packets within the "ZCom_processInput()" function. This can
be exploited to trigger a double free error by sending specially
crafted packets to an application using the "ZCom_processInput()"
function of the library.

The vulnerability is confirmed in version 0.6.7. Other versions may
also be affected.

SOLUTION:
Deny access from untrusted sources to applications linked against the
Zoidcom library.

The vulnerability will reportedly be fixed in version 0.6.8.
