TITLE:
Belkin BullDog Plus HTTP Server Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA34148

VERIFY ADVISORY:
http://secunia.com/advisories/34148/

DESCRIPTION:
Elazar Broad has discovered a vulnerability in Belkin BullDog Plus,
which can be exploited by malicious people to cause a DoS (Denial of
Service) or to potentially compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the included
HTTP server. This can be exploited to cause a stack-based buffer
overflow via specially crafted Base64-encoded data passed during HTTP
authentication.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in version 4.0.2 build 1219. Other
versions may also be affected.

SOLUTION:
Disable the included HTTP server.

PROVIDED AND/OR DISCOVERED BY:
