CVE-2026-25967: ImageMagick has stack buffer overflow in FTXT reader via oversized integer field

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-15, a stack-based buffer overflow exists in the ImageMagick FTXT image reader. A crafted FTXT file can cause out-of-bounds writes on the stack, leading to a crash. Version 7.1.2-15 contains a patch.

Security readout for executives and security teams

Plain-English summary

ImageMagick before 7.1.2-15 can crash when processing a specially crafted FTXT image file. Organizations using ImageMagick in upload, conversion, or automation pipelines should treat this as urgent because image processing often handles untrusted files at scale.

Executive priority

Patch on a high-priority operational timeline, especially for systems processing external files. The strongest supported risk is service disruption or integrity impact from crafted image input, not confirmed active exploitation.

Technical view

The FTXT reader has a stack-based buffer overflow caused by an oversized integer field, producing out-of-bounds stack writes. The published CVSS is 7.4 high, with high integrity and availability impact. The cited sources name ImageMagick versions before 7.1.2-15 as affected and state 7.1.2-15 contains the patch.

Likely exposure

Exposure is most likely where ImageMagick processes user-supplied or externally sourced FTXT files, including web uploads, media conversion services, batch image pipelines, and backend document-processing workflows.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. It supports crafted-file triggering and crash impact, but does not provide confirmed in-the-wild exploitation.

Researcher notes

Key evidence is limited to the CVE record and ImageMagick advisory. Do not assume broader formats, products, or remote code execution beyond the stated stack overflow, out-of-bounds writes, crash, and CVSS integrity/availability impact.

Mitigation direction

  • Upgrade ImageMagick to version 7.1.2-15 or later.
  • Prioritize internet-facing or automated image-processing systems first.
  • Temporarily restrict untrusted FTXT processing until patched.
  • Check vendor and distribution advisories for packaged backports.
  • Restart services that load ImageMagick libraries after updating.

Validation and detection

  • Inventory ImageMagick versions across servers, containers, and build images.
  • Confirm no deployed runtime reports a version earlier than 7.1.2-15.
  • Identify services that process uploaded or external image files.
  • Review logs for crashes in ImageMagick FTXT processing paths.
  • Verify package advisories if using distribution backported fixes.

Stack-based Buffer Overflow

Stack-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
