Vulnerability details

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the png_image_finish_read() function when processing 16-bit interlaced PNGs with 8-bit output format. A remote attacker can pass a specially crafted image file to the application, trigger a 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.
