Description

Foxit PDF Reader v9.0.1.1049 has a Use-After-Free vulnerability
in the Text Annotations component and the TypedArray's use
uninitialized pointers.

The vulnerabilities can be combined to leak a vtable memory address,
which can be adjusted to point to the base address of the executable.
A ROP chain can be constructed that will execute when Foxit Reader
performs the UAF.

This module has been tested on Windows 7 x64, Windows 10 Pro x64
Build 17134, and Windows 10 Enterprise x64. Windows 10 Enterprise
must have insecure logons enabled for the exploit to work as expected.
