CVE-2026-28494

HIGH

ImageMagick vulnerable to stack corruption through long morphology kernel names or arrays

Published March 12, 2026Updated March 14, 2026Source: osv

Summary

A stack buffer overflow exists in ImageMagick's morphology kernel parsing functions. User-controlled kernel strings exceeding a buffer are copied into fixed-size stack buffers via memcpy without bounds checking, resulting in stack corruption.

Remediation

Upgrade to the fixed version using your package manager.
