CVE reference:CVE-2007-0325


Description:
Some vulnerabilities have been discovered in Trend Micro OfficeScan, which can be exploited by malicious people to compromise a user's system.

The vulnerabilities are caused due to boundary errors within the OfficeScan Corp Edition Web-Deployment SetupINI ActiveX control (OfficeScanSetupINI.dll) on an OfficeScan client when attempting to display a list of configuration settings. This can be exploited to cause stack-based buffer overflows by passing overly long properties when a user e.g. visits a malicious web site.

Successful exploitation allows execution of arbitrary code, but requires that OfficeScan client was installed using web deployment.

The vulnerabilities reportedly affect the following products:
* OfficeScan versions 7.3, 7.0, 6.5, and 5.58.
• Client Server Messaging Security versions 3.5, 3.0, and 2.0.

Solution:
Apply patches.
