Doc Text:
A flaw was found in ImageMagick. An attacker can exploit this vulnerability by providing a specially crafted image. This crafted image can trigger an infinite loop within the JPEG encoder, causing the software to consume 100% of the CPU and become unresponsive. This leads to a Denial of Service (DoS), preventing legitimate users from accessing the image processing functionality.

Description OSIDB Bzimport 2026-02-24 03:01:59 UTC 
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.
