CVE-2017-12671
In ImageMagick 7.0.6-3, a missing NULL assignment was found in coders/png.c, leading to an invalid free in the function RelinquishMagickMemory in MagickCore/memory.c, which allows attackers to cause a denial of service.
Does this matter?
Lower severity and a low EPSS score (1.11%). Track it; it rarely justifies an emergency change on its own.
