DESCRIPTION:
A vulnerability has been reported in Microsoft Visual Basic for
Applications and Microsoft Office, which can be exploited by
malicious people to compromise a user's system.

The vulnerability is caused due to the application loading
unspecified libraries in an insecure manner. This can be exploited to
load an arbitrary library by tricking a user into opening an Office
file located on a remote WebDAV or SMB share.

Successful exploitation allows execution of arbitrary code.

actively exploited in targeted attacks.
