Multiple Vulnerabilities in Foxit Reader and Foxit Phantom PDF
Original Issue Date:December 21, 2020
Severity Rating: MEDIUM
Software Affected

Overview
Multiple vulnerabilities has been reported in Foxit Reader and Foxit Phantom PDF for windows where a null pointer access/dereference while opening a crafted PDF file lead to application crash and DoS.
Description
The application could be exposed to Denial of Service vulnerability and crash when opening certain PDF files that contained illegal value in the /Size entry of the Trail dictionary. This occurs due to the array overflow as the illegal value in the /Size entry causes an error in initializing the array size for storing the compression object streams, and an object number which is larger than the initialization value is used as the array index while parsing the cross-reference streams.
Successful exploitation of this vulnerability could allow the attacker to cause denial-of-service in Foxit Reader and Foxit Phantom PDF.
