ImageMagick: Infinite Loop in JPEG Encoder Can Cause CPU Consumption
CVE-2026-26283
GHSA-gwr3-x37h-h84v
CVE-2026-26283
Summary
ImageMagick, a popular image editing software, may get stuck and consume 100% CPU with a malicious image file. This can cause the program to freeze, also known as a Denial of Service. Update to version 7.1.2-15 or 6.9.13-40 to fix the issue.

Original title
ImageMagick has possible infinite loop in JPEG encoder when using `jpeg:extent`
Original 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 `continue` statement in the JPEG extent binary search loop in the jpeg encoder causes an infinite loop when writing persistently fails. An attacker can trigger a 100% CPU consumption and process hang (Denial of Service) with a crafted image. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
