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

1) Office applications load certain libraries in an insecure 
manner,
which can be exploited to load arbitrary libraries by tricking 
a user
into e.g. opening a Word document located on a remote WebDAV or 
SMB
share.

2) An error when handling dereferencing data structures during
parsing of graphic objects in Office files can be exploited via 
e.g.
a specially crafted Excel file.

Successful exploitation of the vulnerabilities allows execution 
of
arbitrary code.

SOLUTION:
Apply patches.
