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.","cvss_v4":{"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","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-835"],"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"],"products":["image-size:image-size"],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2025-71330","score":0.0043,"percentile":0.36998,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-w3rx-r6r6-pgpr","url":"https://osv.dev/vulnerability/GHSA-w3rx-r6r6-pgpr","summary":"image-size: ICNS parser allows denial of service through an infinite loop","modified":"2026-09-24T18:30:11.322772203Z","packages":[{"ecosystem":"npm","name":"image-size","purl":"pkg:npm/image-size","ranges":[">=0.6.3 <2.0.3"],"fixed":["2.0.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
