SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/29831/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
BigAnt Messenger 2.x
http://secunia.com/product/18400/

DESCRIPTION:
Matteo Memelli has discovered a vulnerability in BigAnt Messenger,
which can be exploited by malicious people to compromise a vulnerable
system.

The vulnerability is caused due to a boundary error in the AntServer
Module (AntServer.exe) and can be exploited to cause a stack-based
buffer overflow e.g. by sending a specially crafted, overly long HTTP
GET request to default port 6080/TCP.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 2.2. Other versions may
also be affected.

SOLUTION:
Restrict network access to the AntServer Module.
