MS10-091: Vulnerabilities in the OpenType Font (OTF) Driver Could Allow Remote Code Execution (2296199)

This script is Copyright (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

The remote Windows host contains a font driver that allows arbitrary
code execution.

Description :

The remote Windows host contains a version of the OpenType Font (OTF)
Format Driver that is affected by two vulnerabilities :

- The driver does not properly index an array when
parsing OpenType fonts, which could allow a remote
attacker to run arbitrary code in kernel mode.
(CVE-2010-3956)

- The driver does not properly reset a pointer when
freeing memory, resulting in a 'double free' condition,
which could allow a remote attacker to run arbitrary
code in kernel mode. (CVE-2010-3957)

- The driver does not properly parse the CMAP table when
rendering a specially crafted OpenType font, which
could allow a local attacker to run arbitrary code in
kernel mode. (CVE-2010-3959)
