Lifecycle Timeline
1DescriptionCVE.org
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-50 and 7.1.2-25, an incorrect loop in the ICON decoder can result in an out of bounds heap write resulting in a crash. This issue has been patched in versions 6.9.13-50 and 7.1.2-25.
AnalysisAI
Out-of-bounds heap write in ImageMagick's ICON decoder allows remote attackers to crash the application by supplying a maliciously crafted ICON file processed by versions prior to 6.9.13-50 and 7.1.2-25. The flaw stems from an incorrect loop condition during ICON parsing, leading to memory corruption and denial of service. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target application must invoke ImageMagick (binary or library binding such as MagickWand, IMagick, RMagick, or Wand) to decode an attacker-supplied file that ImageMagick parses as ICON format - note that ImageMagick auto-detects format by content, so the file extension does not have to be .ico. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/C:N/I:N/A:H, 7.5 High) indicates remote, unauthenticated, low-complexity exploitation with availability-only impact - consistent with a crash rather than code execution. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker uploads a maliciously crafted ICON file to a web application that uses ImageMagick to generate thumbnails or convert avatars; when the backend invokes 'magick convert' or the MagickWand library, the ICON decoder's faulty loop writes past the heap buffer and the worker process crashes. Repeated submissions cause persistent denial of service against the image-processing pipeline, potentially exhausting worker pools or triggering supervisor restart loops. … |
| Remediation | Vendor-released patch: upgrade to ImageMagick 6.9.13-50 or 7.1.2-25 (or later) per the GitHub Security Advisory at https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-g22q-f7gc-5jhr. … Detailed patch versions, workarounds, and compensating controls in full report. |
