ImageMagick: Stack buffer overflow in FTXT reader via oversized integer field

  • Disclosed: 24.02.2026
  • Updated: 11.10.2026 11:23

Summary

A stack-based buffer overflow exists in the ImageMagick FTXT image reader. A crafted FTXT file can cause out-of-bounds writes on the stack, leading to a crash.
