Doc Text:
A flaw was found in image-size. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by supplying specially crafted JXL, HEIF, or JP2 image files that contain zero-sized boxes. The `findBox` function, responsible for image validation, enters an infinite loop when processing these malicious files, leading to an application hang. This can disrupt the availability of services relying on the image-size component.

Description OSIDB Bzimport 2026-06-09 21:01:36 UTC 
image-size 1.1.0 before 1.2.1 and 2.0.0 before 2.0.2 contain a denial of service vulnerability in the findBox function when processing specially crafted images with zero-sized boxes. Remote attackers can cause application hang by supplying malicious JXL, HEIF, or JP2 image files with box size zero, triggering infinite loops during image validation.
