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

1) The vulnerability is caused due to MSO.DLL loading libraries (e.g.
".dll") in an insecure manner when attempting to validate an opened
file. This can be exploited to load arbitrary libraries by tricking a
user into e.g. opening a PPT file located on a remote WebDAV or SMB
share.

2) An error when parsing unspecified data can be exploited to
dereference an uninitialised value as an object pointer via e.g. a
specially crafted Word document.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code.

SOLUTION:
Apply patches.
