DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious, local users to gain escalated
privileges and potentially by malicious people to compromise a user's
system.

1) An error in the parsing of OTF (OpenType Font) files can be
exploited by loading a properly formatted font and then reload it
with specially crafted offset and length fields for the head table of
the font.

2) An error when allocating memory during parsing of OTF files can be
exploited to corrupt memory.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code with kernel privileges. For third-party web browsers
natively rendering OpenType Fonts (OTF), this may be exploited
remotely when a user visits a web page embedding a specially crafted
font.

SOLUTION:
Apply patches.
