TITLE:
Cafu Denial of Service and Format String Vulnerabilities
SECUNIA ADVISORY ID:
SA39054
VERIFY ADVISORY:
http://secunia.com/advisories/39054/
DESCRIPTION:
Luigi Auriemma has reported two vulnerabilities in Cafu, which can be
exploited by malicious people to cause a DoS (Denial of Service) or
potentially compromise an application using the engine.
1) A NULL-pointer dereference when processing incomplete
"CS0_RemoteConsoleCommand" packets can be exploited to crash an
affected server.
2) A format string error when a client e.g. prints chat messages can
be exploited to cause a crash or potentially corrupt memory via a
specially crafted packet.
Successful exploitation of this vulnerability may allow execution of
arbitrary code.
The vulnerabilities are reported in version 9.06. Other versions may
also be affected.
SOLUTION:
Use the engine in trusted networks only.
