1) Integer underflow (CVE-ID: CVE-2026-62289)

CWE-ID: CWE-191 - Integer underflow

CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to integer underflow in the Fraction constructor when processing a crafted HEIF/AVIF file through the tiling API with process_image_transformations=1. A remote attacker can supply a specially crafted file to cause a denial of service.

User interaction is required to open the crafted file, or the issue can be triggered server-side when uploaded content is processed automatically.
