CVE-2018-6405

MEDIUMEPSS 74th pctl
6.5
CVSS v3
NVD

Description

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.
