Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to type confusion error. A remote attacker can execute certain XFA FormCalc functions in crafted PDF files since the application could transform non-CXFA_Object to CXFA_Object by force without judging the data type and use the discrepant CXFA_Object directly.
Successful exploitation of the vulnerability may result in system compromise.
