TippingPoint has reported some vulnerabilities in Macrovision Update Service and FLEXnet Connect, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors in the boisweb.dll ActiveX control when handling the "DownloadAndExecute()" and "AddFileEx()" methods. This can be exploited to cause stack-based buffer overflows via overly long arguments.
Successful exploitation allows execution of arbitrary code.
Solution: The vendor has reportedly issued an updated version of the agent.
