Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Magick.NET-Q16 packages (AnyCPU, HDRI, OpenMP and architecture-specific variants for arm64, x64 and x86) before 14.10.3 are vulnerable. A `continue` statement in the JPEG extent binary search loop can cause an infinite loop when writing fails persistently, so an attacker supplying a crafted image can consume 100% CPU and hang the process. Upgrade to version 14.10.3.
