image-size 2.0.2 Denial of Service via Infinite Loop in JXL/HEIF Parser_CVE-2025-71329

{
    "lastseen": "",
    "description": "image-size through 2.0.2 contains a denial of service vulnerability that allows remote attackers to permanently block the Node.js event loop by supplying a specially crafted image buffer with a zero-valued size field in a recognized box-type. Attackers can trigger an infinite loop in the JXL or HEIF image parsers by providing a crafted image containing a box with a size of zero, causing the offset to never advance and permanently hanging the application.",
