Microsoft Windows OpenType Font Driver Three Vulnerabilities

-

Description


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

1) An array indexation error within the OpenType Font (OTF) driver while parsing OpenType fonts can be exploited to corrupt memory.

2) A double-free error due to the OpenType Font (OTF) driver not properly resetting a pointer when freeing memory can be exploited to corrupt memory via a specially crafted OpenType font.

3) An unspecified error in the OpenType Font (OTF) driver when parsing the CMAP table of an OpenType font can be exploited to corrupt memory.

Successful exploitation allows execution of arbitrary code in kernel mode.


Solution:
Apply the patches.
