CVE-2018-20189 is a vulnerability of currently unknown severity. In GraphicsMagick 1.3.31, the ReadDIBImage function of coders/dib.c has a vulnerability allowing a crash and denial of service via a dib file that is crafted to appear with direct pixel values and also colormapping (which is not available beyond 8-bits/sample), and therefore lacks indexes initialization.. EPSS estimates a 2.28% chance of exploitation in the next 30 days.
