CVE-2012-3438: Graphicsmagick

Medium severity, CVSS 4.3. EPSS: 2.5% chance of exploitation in the next 30 days.

The Magick_png_malloc function in coders/png.c in GraphicsMagick 6.7.8-6 does not use the proper variable type for the allocation size, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG file that triggers incorrect memory allocation.
