DESCRIPTION:
Secunia Research has discovered a vulnerability in Trend Micro
OfficeScan, which can be exploited by malicious people to compromise
a vulnerable system.

A boundary error in cgiRecvFile.exe can be exploited to cause a

crafted, overly long "ComputerName" parameter.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 7.3 with Patch 4 build 1362
applied and also affects OfficeScan version 7.0 and 8.0, and Client
Server Messaging Security version 3.6, 3.5, 3.0, and 2.0.
