Vavoom Two Denial of Service Vulnerabilities

SECUNIA ADVISORY ID:
SA19388

VERIFY ADVISORY:
http://secunia.com/advisories/19388/

CRITICAL:
Moderately critical

IMPACT:
DoS

WHERE:
>From remote

SOFTWARE:
Vavoom 1.x
http://secunia.com/product/8925/

DESCRIPTION:
Luigi Auriemma has reported two vulnerabilities in Vavoom, which can
be exploited by malicious people to cause a DoS (Denial of Service).

1) An error within the handling of asynchronous socket connections
can cause an infinite loop when processing a packet with no data or
with a size larger than 4096 bytes. This can be exploited to cause
users to be unable to connect to the server until it is restarted

2) A boundary error exists within the handling of compressed packets.
This can be exploited to cause a buffer overflow and crashes the
server via a specially-crafted "comprLength" value in the packet.

The vulnerabilities have been reported in version 1.19.1 and prior.

SOLUTION:
Host network games only within trusted networks.
