Lifecycle Timeline
3Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, 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. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

Remediation
Within 24 hours: Identify all systems and applications using ImageMagick through asset inventory and dependency scanning; restrict network access to ImageMagick services where possible. Within 7 days: Implement input validation to reject oversized or malformed kernel strings; deploy WAF rules to block suspicious ImageMagick requests; consider disabling morphology kernel parsing if not business-critical. …
