Descriptions
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.0.1.1049. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of Text Annotations. When setting the point attribute, the process does not properly validate the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5620.

Foxit PDF Reader version 9.0.1.1049 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.
