ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32, an unauthenticated adjacent-network client can repeatedly connect to the distributed pixel cache server and exhaust its available connections, causing denial of service. This issue is fixed in version 7.1.2-32.
