Received Received - Intake
Heap Information Disclosure in ImageMagick PSD Handler

Publication date: 2026-02-24

Last updated on: 2026-02-24

Assigner: GitHub, Inc.

Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap information disclosure vulnerability exists in ImageMagick's PSD (Adobe Photoshop) format handler. When processing a maliciously crafted PSD file containing ZIP-compressed layer data that decompresses to less than the expected size, uninitialized heap memory is leaked into the output image. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

Executive Summary

[{'type': 'paragraph', 'content': "CVE-2026-24481 is a high-severity heap information disclosure vulnerability in ImageMagick's PSD (Adobe Photoshop) format handler. It occurs when ImageMagick processes a maliciously crafted PSD file that contains ZIP-compressed layer data which decompresses to less than the expected size. This causes uninitialized heap memory to be leaked into the output image."}, {'type': 'paragraph', 'content': 'The vulnerability involves an out-of-bounds read (CWE-125) where data is read beyond the intended buffer boundaries. It can be exploited remotely without any privileges or user interaction.'}] [1]

Impact Analysis

This vulnerability can lead to the exposure of sensitive server memory data because uninitialized heap memory is leaked into the output image when processing crafted PSD files.

Since the vulnerability impacts confidentiality without affecting integrity or availability, attackers could potentially gain access to sensitive information stored in memory, which could be used for further attacks or data breaches.

Exploitation requires no privileges or user interaction and can be triggered remotely, increasing the risk of unauthorized data disclosure.

Detection Guidance

This vulnerability can be detected by identifying the presence of vulnerable versions of ImageMagick on your system, specifically versions prior to 7.1.2-15 and 6.9.13-40.

You can check the installed ImageMagick version using the following command:

  • magick -version

Additionally, monitoring for suspicious PSD files containing ZIP-compressed layer data that decompresses to less than the expected size may help detect exploitation attempts, but no specific detection commands are provided.

Mitigation Strategies

The immediate mitigation step is to upgrade ImageMagick to a patched version that addresses this vulnerability.

  • Upgrade to ImageMagick version 7.1.2-15 or later.
  • Alternatively, upgrade to version 6.9.13-40 or later if using the 6.x branch.

These versions contain patches that fix the heap information disclosure vulnerability in the PSD format handler.
