CVE-2019-11472: Divide by Zero
ImageMagick is vulnerable to a denial of service, caused by a divide-by-zero error in the ReadXWDImage function in coders/xwd.c. By persuading a victim to open a specially-crafted XWD image file, a remote attacker could exploit this vulnerability to cause the application to crash.
Other sources
ReadXWDImage in coders/xwd.c in the XWD image parsing component of ImageMagick 7.0.8-41 Q16 allows attackers to cause a denial-of-service (divide-by-zero error) by crafting an XWD image file in which the header indicates neither LSB first nor MSB first.
