TITLE:
BigAnt Messenger AntServer Module Buffer Overflow Vulnerability
SECUNIA ADVISORY ID:
SA36704
VERIFY ADVISORY:
http://secunia.com/advisories/36704/
DESCRIPTION:
Blake 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) when processing HTTP requests. This can be
exploited to cause a stack-based buffer overflow via an overly large
HTTP GET request sent to an affected server.
Successful exploitation may allow execution of arbitrary code.
This is related to vulnerability #1 in:
SA29831
The vulnerability is confirmed in version 2.50. Other versions may
also be affected.
SOLUTION:
Restrict network access to the TCP port on which AntServer is
listening (TCP port 6660 by default).
