-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of HP 3COM/H3C Intelligent Management Center.
Authentication is not required to exploit this vulnerability. 

The flaw exists within the img.exe component which listens by default on
TCP port 8800. When handling the a packet type the process uses a user
provided length value in an arithmetic operation resulting in integer
wrapping. The process then copies user supplied data into a fixed-length
buffer on the heap. A remote attacker can exploit this vulnerability to
execute arbitrary code under the context of the SYSTEM user.

-- Vendor Response:
 [May 31, 2011] - This vulnerability is being disclosed publicly
without a patch in accordance with the ZDI 180 day deadline.

-- Mitigation:
As the affected component is the 'core' process for IMC, we recommend
either disabling this service entirely until a vendor patch is available
or denying incoming connections to 8800/tcp, this is the remote vector
into the vulnerable code.
