Versions of astral-tokio-tar prior to 0.5.6 contain a boundary parsing vulnerability that allows attackers to smuggle additional archive entries by exploiting inconsistent PAX/ustar header handling. When processing archives with PAX-extended headers containing size overrides, the parser incorrectly advances stream position based on ustar header size (often zero) instead of the PAX-specified size, causing it to interpret file content as legitimate tar headers. This issue has been patched in version 0.5.6. There are no workarounds.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","score":8.1,"severity":null}],"references":["https://github.com/astral-sh/tokio-tar/security/advisories/GHSA-j5gw-2vrg-8fgx","https://github.com/astral-sh/uv/security/advisories/GHSA-w476-p2h3-79g9","https://github.com/astral-sh/tokio-tar/commit/22b3f884adb7a2adf1d3a8d03469533f5cbc8318","https://edera.dev/stories/tarmageddon","https://github.com/edera-dev/cve-tarmageddon"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2025-35176","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 21, 2025, 4:13:02 PM","dateUpdated":"Oct 22, 2025, 1:23:33 PM"},"relatedAdvisories":[{"id":"openSUSE-SU-2025:15658-1","title":"python311-uv-0.9.5-1.1 on GA media","vulnerabilityIds":["CVE-2025-62518"]},{"id":"openSUSE-SU-2026:20026-1","title":"Security update for python-uv","vulnerabilityIds":["CVE-2025-58160","CVE-2025-62518"]},{"id":"msrc_CVE-2025-62518","title":"astral-tokio-tar Vulnerable to PAX Header Desynchronization","vulnerabilityIds":["CVE-2025-62518"]},{"id":"SUSE-SU-2026:20077-1","title":"Security update for python-uv","vulnerabilityIds":["CVE-2025-58160","CVE-2025-62518"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
