Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Magick.NET-Q8 and Magick.NET-Q16 packages (all x64, arm64, x86 and OpenMP variants) before 14.10.2 are vulnerable to a stack overflow caused by infinite recursion in the MSL script processor when a write or read command references MSL files, including self-referencing or indirectly looping files. An attacker who can supply a crafted MSL file to an application that processes it can crash the process by exhausting the stack. Upgrade to version 14.10.2. The source gives few details on the exact trigger conditions.
