Doc Text:
It was discovered that ImageMagick did not properly sanitize certain input before using it to invoke processes. A remote attacker could create a specially crafted image that, when processed by an application using ImageMagick or an unsuspecting user using the ImageMagick utilities, would lead to arbitrary execution of shell commands with the privileges of the user running the application.

Description Andrej Nemec 2016-05-30 10:53:02 UTC 
All existing releases of GraphicsMagick and ImageMagick support a file open syntax where if the first character of the file specification is a '|', then the remainder of the filename is passed to the shell for execution using the POSIX popen(3C) function.  File opening is handled by an OpenBlob() function in the source file blob.c. Unlike the vulnerability described by CVE-2016-3714, this functionality is supported by the core file opening function rather than a delegates subsystem usually used to execute external programs.

Comment 5 Tomas Hoger 2016-06-15 11:57:05 UTC 
Patch attached to the oss-security post linked in comment 0 only disabled popen support.  This GraphicsMagick upstream patch removes popen support completely:
