DESCRIPTION:
Parvez Anwar has discovered a vulnerability in the WebEx Meeting
Manager WebexUCFObject ActiveX control, which can be exploited by
malicious people to compromise a user's system.

The vulnerability is caused due to the WebexUCFObject ActiveX control
(atucfobj.dll) loading libraries (e.g. wbxtrace.dll) in an insecure
manner. This can be exploited to load arbitrary libraries by e.g.
embedding the ActiveX control into a Microsoft Word document and
tricking a user into opening the document from a remote WebDAV or SMB
share.

The vulnerability is confirmed in atucfobj.dll version
20.2009.2706.1025 included in the WebEx Meeting Manager ActiveX
package. Other versions may also be affected.

SOLUTION:
The vendor has planned the rollout of an updated version for December
4th, 2010. Please contact the vendor for additional details.
