Security readout for executives and security teams
Plain-English summary
ImageMagick versions before 7.1.2-15 and 6.9.13-40 can read past a memory buffer when handling certain DICOM medical image files. This may crash an application or expose small amounts of heap memory. Organizations using ImageMagick in automated image-processing services should prioritize updating, especially where untrusted files are accepted.
Executive priority
Treat this as a near-term patching item for systems processing untrusted images. It is not described as actively exploited, but the network-reachable, no-authentication CVSS profile increases operational risk for public upload workflows.
Technical view
CVE-2026-25982 is a CWE-125 heap out-of-bounds read in ImageMagick's DICOM decoder, coders/dcm.c ReadDCMImage. The advisory states a decoder loop reads incorrect bytes per iteration under a specific configuration, potentially causing denial of service or information disclosure. CVSS 3.1 is 6.5, network attack vector, low complexity, no privileges or user interaction.
Likely exposure
Exposure is most likely in applications, pipelines, or web services that use ImageMagick to process DICOM files, especially from external users or partners. Affected versions are ImageMagick 7.0.0 through before 7.1.2-15, and 6.x before 6.9.13-40.
Exploitation context
The source bundle does not indicate known active exploitation, and KEV is false. The issue can be triggered during DICOM parsing; impact is limited to crash or possible heap memory disclosure as described by the advisory. No public exploit status is provided in the cited sources.
Researcher notes
Analysis is limited to the provided CVE and GitHub advisory data. The affected component is ReadDCMImage in coders/dcm.c. The stated fixed versions are 7.1.2-15 and 6.9.13-40. No additional affected forks, downstream packages, exploit availability, or workaround details are provided in the sources.
Mitigation direction
- Upgrade ImageMagick to 7.1.2-15, 6.9.13-40, or later supported vendor packages.
- Inventory services and containers that process images with ImageMagick.
- Restrict or disable DICOM processing where it is not business-required.
- Limit untrusted file uploads to trusted formats until patched.
- Monitor vendor advisory pages for distribution-specific package updates.
Validation and detection
- Check installed ImageMagick versions across servers, containers, and build images.
- Confirm production packages are at least 7.1.2-15 or 6.9.13-40.
- Identify applications that call ImageMagick on uploaded or partner-supplied DICOM files.
- Review crash logs for recent ImageMagick failures during DICOM processing.
- Verify package managers or SBOMs no longer report affected versions.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
