ImageMagick has NULL Pointer Dereference in ClonePixelCacheRepository via crafted image

  • Disclosed: 24.02.2026
  • Updated: 11.10.2026 11:23

A NULL pointer dereference in ClonePixelCacheRepository allows a remote attacker to crash any application linked against ImageMagick by supplying a crafted image file, resulting in Denial of Service.
