CVE-2018-6405
The previous pointer is lost, which leads to a memory leak.
MEDIUM 6.5EPSS 1.67%
Does this matter?
Lower severity and a low EPSS score (1.67%). Track it; it rarely justifies an emergency change on its own.
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.
