CVE-2018-6405

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.

En la función ReadDCMImage en coders/dcm.c en ImageMagick, en versiones anteriores a la 7.0.7-23, cada variable redmap, greenmap y bluemap puede ser sobrescrita por un nuevo puntero. El puntero anterior se pierde, lo que conduce a una fuga de memoria. Esto permite que atacantes remotos provoquen una denegación de servicio.
