Description

A vulnerability has been identified in an ActiveX component which is installed and marked as "safe" when using Symantec's online Security Check.

The problem is that the "CompareVersionStrings" function doesn't verify input properly. This allows malicious web sites to activate the ActiveX component and supply very long maliciously crafted strings which possibly could execute arbitrary code.

Because the ActiveX component has been marked as safe, it may be activated by any other web site without warning or prompting the user.


Solution
Remove "Symantec RuFSI Utility Class" or "Symantec RuFSI Registry Information Class" from your system.
