ImageMagick: Heap overflow in sun decoder on 32-bit systems may result in out of bounds write

  • Disclosed: 24.02.2026
  • Updated: 11.10.2026 11:23

An Integer Overflow vulnerability exists in the sun decoder. On 32-bit systems/builds, a carefully crafted image can lead to an out of bounds heap write.
