Description

The vulnerability allows a remote attacker to obtain potentially sensitive information and perform a denial of service (DoS) attack.

The vulnerability exists due to an error when executing certain XFA functions in crafted PDF files since the application could transform CXFA_Object to CXFA_Node without judging the data type and use the discrepant CXFA_Node directly. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger out-of-bounds read to access arbitrary data and perform a denial of service (DoS) attack.

Mitigation
Update to version 9.4.

Vulnerable software versions

Foxit PDF Reader for Windows: 9.0 - 9.3.0.10826

Foxit PDF Editor (formerly Foxit PhantomPDF): 9.0 - 9.3.0.10826
