ImageMagick security update (CVE-2026-93586)
Use ImageMagick to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. Security Fix(es): ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a use-after-free vulnerability in the ImagesToBlob method, caused by a pointer that is not updated correctly. Exploitation may result in a limited availability impact (e.g., a crash of the affected process). The issue is fixed in versions 7.1.2-31 and 6.9.13-56.(CVE-2026-93586) ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a policy bypass in the PCD (and, per the upstream advisory, CUBE and HALD) coder: when a specific command line option is supplied, the decoder does not check a configured resource limit, which can result in extra memory allocation. A local user able to pass command line options to ImageMagick can therefore exceed the intended memory policy limit, causing a limited availability impact. The issue is fixed in 7.1.2-31 and 6.9.13-56.(CVE-2026-93587) ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferenced, which can lead to a denial of service (application crash) when processing a specially crafted or sufficiently large PNM image.(CVE-2026-93588) ImageMagick before 7.1.2-31 and 6.9.13-56 contains a division-by-zero flaw in the FLIF encoder. An incorrect value for ticks per second in the image being encoded causes a divide-by-zero and crashes the encoder, resulting in a denial of service. The issue is fixed in 7.1.2-31 and 6.9.13-56.(CVE-2026-93589)
AI Analysis
Technical Summary
A use-after-free vulnerability exists in the ImagesToBlob method of ImageMagick versions prior to 7.1.2-31 and 6.9.13-56. The vulnerability is caused by a pointer that is not updated correctly, which may lead to a crash of the affected process. The flaw has been addressed and fixed in the specified versions.
Potential Impact
Exploitation of this vulnerability may cause a limited availability impact, such as a crash of the ImageMagick process. There is no indication of confidentiality or integrity impact.
Mitigation Recommendations
A fix is available in ImageMagick versions 7.1.2-31 and 6.9.13-56. Users should upgrade to these or later versions to remediate the vulnerability.
