TITLE:
Vavoom Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA26554

VERIFY ADVISORY:
http://secunia.com/advisories/26554/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

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

DESCRIPTION:
Luigi Auriemma has reported some vulnerabilities in Vavoom, which can
be exploited by malicious people to cause a DoS (Denial of Service) or
potentially compromise a vulnerable system.

1) A format string error exists within the "SAY" command in
sv_main.cpp. This can be exploited to crash the server or potentially
execute arbitrary code by sending a specially crafted chat message
containing format specifiers.

2) A boundary error exists within the "VThinker::BroadcastPrintf()"
function in p_thinker.cpp. This can be exploited to cause a buffer
overflow by sending an overly long chat message.

Successful exploitation may allow the execution of arbitrary code.

3) An assertion error exists within the "VStr::Resize()" function in
str.cpp. This can be exploited to crash a server by e.g. sending a
specially crafted UDP datagram to the server (default port 26000).

SOLUTION:
Use in trusted network environments only.
