Macrovision FLEXnet boisweb.dll ActiveX Control Buffer Overflows

SECUNIA ADVISORY ID:
SA25509

VERIFY ADVISORY:
http://secunia.com/advisories/25509/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
Macrovision FLEXnet Connect 6.x
http://secunia.com/product/13552/
Macrovision Update Service 3.x
http://secunia.com/product/14426/
Macrovision Update Service 4.x
http://secunia.com/product/14427/
Macrovision Update Service 5.x
http://secunia.com/product/14428/

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.
