DESCRIPTION:
Two vulnerabilities have been discovered in Microsoft WMI
Administrative Tools, which can be exploited by malicious people to
compromise a user's system.

The vulnerabilities are caused due to the "AddContextRef()" and
"ReleaseContext()" methods in the WMI Object Viewer Control
(WBEM.SingleViewCtrl.1) using a value passed in the "lCtxHandle"
parameter as an object pointer.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities are confirmed in version 1.1 (WBEMSingleView.ocx
1.50.1131.0). Other versions may also be affected.

SOLUTION:
Set the kill-bit for the affected ActiveX control.

PROVIDED AND/OR DISCOVERED BY:
WooYun

Additional information about vulnerability in the "ReleaseContext()"
method provided by Secunia Research.
