CVE-2026-26283 | ImageMagick has possible infinite loop in JPEG encoder when using `jpeg:extent`

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.

6.2 3.1 MEDIUM

Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
