Secunia Advisory SA25509

Where:

From remote

Impact:

System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


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.

Provided and/or discovered by:
Pedram Amini, TippingPoint Security Research Team.
