Machine-written summary

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

The Magick.NET NuGet packages for x64 and arm64 (Q8, Q16, Q16-HDRI, and OpenMP variants) are affected in versions before 14.8.2, which contain ImageMagick's BlobStream code. A forward seek past the end of a memory-backed blob followed by a write can cause a heap out-of-bounds write, which may lead to memory corruption or potentially code execution. Upgrade to version 14.8.2 or later. The source gives few details on how an attacker would reach this path in practice.
