CVE-2018-6405
Published: 30 January 2018
In the ReadDCMImage function in coders/dcm.c in ImageMagick before 7.0.7-23, each redmap, greenmap, and bluemap variable can be overwritten by a new pointer. The previous pointer is lost, which leads to a memory leak. This allows remote attackers to cause a denial of service.
