Description

This module exploits a vulnerability found in the ActiveX component of Adobe
Flash Player before 11.3.300.271. By supplying a specially crafted .otf font file
with a large nTables value in the 'kern' header, it is possible to trigger an
integer overflow, which results in remote code execution under the context of the
user. This vulnerability has also been exploited in the wild in limited targeted
attacks. Please note in order to ensure reliability, the exploit is forced to
modify your URIPATH parameter to less than 3 characters, which may cause possible
URIPATH collisions.
