Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the fz_append_display_node located at fitz/list-device.c, allowing remote attackers to execute arbitrary code via a crafted PDF file with a large BDC property name that overflows the allocated size of a display list node. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
