Attackers can craft an ICNS buffer containing valid magic bytes and a zero-valued entry length field to trigger an infinite loop in the ICNS parser, as the offset is never incremented when the entry length field is 0, causing the while loop condition to remain true indefinitely.","state":0,"publishedAt":"2026-06-10T14:16:30.387+00:00","modifiedAt":"2026-10-12T22:10:00.247+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1 · disclosure@vulncheck.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://joshua.hu/image-size-infinite-loop-dos-vulnerabilities","https://web.archive.org/web/20260224152152/https://github.com/image-size/image-size/pull/439","https://www.vulncheck.com/advisories/image-size-denial-of-service-via-malformed-icns-image-parsing"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-71330","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-835"],"productCriteria":["cpe:2.3:a:image-size:image-size:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-06-10T14:16:30.387","lastModified":"2026-10-12T22:10:00.247"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
