CVE-2012-3437: ImageMagick

Medium severity, CVSS 4.3. EPSS: 2.8% chance of exploitation in the next 30 days.

The Magick_png_malloc function in coders/png.c in ImageMagick 6.7.8 and earlier 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.
