  - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to
    7.1.2-31, a client connected to the distributed pixel cache server can send crafted pixel data that
    triggers an integer-size calculation error and a heap buffer overwrite, crashing the server. This issue is
    fixed in version 7.1.2-31. (CVE-2026-106574)
