CVE-2020-21679

GraphicsMagick is the swiss army knife of image processing. Comprised of 267K physical lines (according to David A. Wheeler's SLOCCount) of source code in the base package (or 1,225K including 3rd party libraries) it provides a robust and efficient collection of tools and libraries which support reading, writing, and manipulating an image in over 89 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, TIFF, and WebP.

Security Fix(es):

Buffer Overflow vulnerability in WritePCXImage function in pcx.c in GraphicsMagick 1.4 allows remote attackers to cause a denial of service via converting of crafted image file to pcx format.(CVE-2020-21679)
