SRC-2020-0017 : Foxit Reader Heap Buffer Overflow Remote Code Execution vulnerability
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Reader. 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 processing of image resources inside of PDF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
Foxit has issued an update to correct this vulnerability. More details can be found at:
