Does this matter?

Lower severity and a low EPSS score (1.22%). Track it; it rarely justifies an emergency change on its own.

Description

A flaw was found in the check_chunk_name() function of pngcheck-2.4.0. An attacker able to pass a malicious file to be processed by pngcheck could cause a temporary denial of service, posing a low risk to application availability.
