TITLE:
C'Nedra "READ_TCP_STRING()" Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA15519

VERIFY ADVISORY:
http://secunia.com/advisories/15519/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
C'Nedra 0.x
http://secunia.com/product/5168/

DESCRIPTION:
Luigi Auriemma has reported a vulnerability in C'Nedra, which can be
exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the network
plugin in the function "READ_TCP_STRING()" in
"game_message_functions.cpp". This can be exploited to cause a buffer
overflow by sending an overly long text string (more than 100 bytes)
to a vulnerable application based on the C'Nedra framework.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been reported in versions 0.4.0 and prior.

SOLUTION:
Use the network plugin on trusted networks only.

PROVIDED AND/OR DISCOVERED BY:
