CVE-2018-16749: Null Pointer Dereference
First published: Sun Sep 09 2018(Updated: )
ImageMagick is vulnerable to a denial of service, caused by a missing NULL check in the ReadOneJNGImage function in coders/png.c. By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause a denial of service condition.
