CVE-2026-48724

Vulnerability

ImageMagick, a widely used image manipulation software, contains a heap buffer overwrite vulnerability in versions prior to 7.1.2-24. This issue occurs when processing an image that utilizes a mask and the Floyd-Steinberg dithering method [1].

Exploitation

An attacker can exploit this vulnerability by providing a specially crafted image file to a vulnerable ImageMagick instance. The vulnerability is triggered during the image processing pipeline when the Floyd-Steinberg dithering method is applied in conjunction with an image mask. No specific privileges or user interaction are mentioned as required for exploitation in the available references [1].

Impact

Successful exploitation of this vulnerability results in a heap buffer overwrite. This can lead to a crash of the ImageMagick process, potentially causing denial of service. Depending on the context in which ImageMagick is used, this could also lead to further security implications such as arbitrary code execution, though this is not explicitly detailed in the provided references [1].

Mitigation

This vulnerability has been patched in ImageMagick version 7.1.2-24. Users are strongly advised to upgrade to this version or a later release to remediate the issue. No workarounds are mentioned in the available references [1].
