Name of the Vulnerable Software and Affected Versions GraphicsMagick versions prior to 1.3.35

Description The issue is related to a heap-based buffer overflow in the coders/png.c component of the GraphicsMagick library, which can be exploited by a remote attacker to cause a denial of service. The ReadMNGImage function in coders/png.c is specifically affected.

Recommendations For versions prior to 1.3.35, update to version 1.3.35 or later to resolve the issue. As a temporary workaround, consider restricting access to the ReadMNGImage function in coders/png.c to minimize the risk of exploitation.
