Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists when executing certain XFA functions in crafted PDF files since the application could transform non-CXFA_Object to CXFA_Object without judging the data type and use the discrepant CXFA_Object to get layout object directly. A remote attacker can trick the victim into opening a specially crafted file, trigger type confusion error and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
Affected software
