Description
PDF Explorer 1.5.66.2 contains a structured exception handler (SEH) overflow vulnerability that allows local attackers to execute arbitrary code by overwriting SEH records with malicious data. Attackers can craft a payload with buffer overflow, NSEH jump, and ROP gadget chains that execute when the Custom fields settings dialog processes the malicious input in the Label field.
