Detailed vulnerability description
The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists due to type confusion when executing certain XFA functions in crafted PDF files since the application can 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 cause the service to crash or execute arbitrary code on the target system.
Successful exploitation of the vulnerability may result in system compromise.
