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

1) Insufficient validation when parsing an Office Art Drawing record,
which contains "msofbtSp" records that specify certain flags can be
exploited to corrupt memory via a specially crafted Office file.

2) A boundary error when parsing RTF (Rich Text Format) formatted
content can be exploited to cause a stack-based buffer overflow via a
specially crafted file.

3) An error handling a large SPID can be exploited to corrupt memory
via a specially crafted file.

4) An error in the drawing exception handling can be exploited to
corrupt memory via a specially crafted file.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.

SOLUTION:
Apply patches.
