In coders/psd.c in ImageMagick 7.0.7-0 Q16, a DoS in ReadPSDLayersInternal() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted PSD file, which claims a large "length" field in the header but does not contain sufficient backing data, is provided, the loop over "length" would consume huge CPU resources, since there is no EOF check inside the loop.

Security readout for executives and security teams

Plain-English summary

This vulnerability lets a malformed Photoshop PSD file make ImageMagick spend excessive CPU while trying to read layer data. The main business risk is service slowdown or outage in systems that process user-supplied images, not data theft or remote code execution based on the provided sources.

Executive priority

Treat this as a targeted availability risk. Prioritize patching internet-facing or customer-upload image processing first, then internal batch systems. Urgency is lower than active exploited code execution, but outages can be material if image processing is business-critical.

Technical view

In ImageMagick 7.0.7-0 Q16, coders/psd.c ReadPSDLayersInternal() loops over a PSD header length value without an EOF check. A crafted PSD can claim a large length while lacking backing data, causing high CPU consumption during parsing.

Likely exposure

Exposure is most likely where ImageMagick processes untrusted PSD files, including upload pipelines, media conversion workers, or distro-packaged ImageMagick installations covered by Ubuntu, Gentoo, or Debian advisories.

Exploitation context

The source bundle describes a crafted-file denial of service. It does not identify active exploitation, public weaponization, authentication requirements, or network reachability. KEV status is false.

Researcher notes

Evidence supports a PSD parser CPU-exhaustion flaw tied to missing EOF handling in ReadPSDLayersInternal(). Sources include upstream issue and commits plus Linux distribution advisories. No CVSS, CWE, complete affected-version matrix, or active exploitation evidence is provided.

Mitigation direction

  • Update ImageMagick using relevant vendor security packages or upstream fixed code.
  • Review Ubuntu, Gentoo, Debian, and upstream ImageMagick guidance for applicable versions.
  • Reduce or block untrusted PSD processing until patched where business impact is high.
  • Run image conversion workloads with resource controls and isolation where available.

Validation and detection

  • Inventory systems and containers that include ImageMagick or distro imagemagick packages.
  • Identify workflows that accept or transform PSD files from untrusted sources.
  • Confirm installed packages include the vendor security updates or upstream fixes.
  • Check monitoring for unusual CPU spikes in ImageMagick image-processing workers.
