{"id":"BIT-python-2025-13462","summary":"tarfile: Skip DIRTYPE normalization during GNU LONGNAME/LONGLINK handling","details":"The \"tarfile\" module would still apply normalization of AREGTYPE (\\x00) blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPE_LONGNAME or GNUTYPE_LONGLINK. This could result in a crafted tar archive being misinterpreted by the tarfile module compared to other implementations.","aliases":["BIT-libpython-2025-13462","BIT-python-min-2025-13462","CVE-2025-13462","PSF-2026-10"],"modified":"2026-03-27T08:48:14.726683Z","published":"2026-03-14T08:49:56.012Z","withdrawn":"2026-03-27T08:48:14.726683Z","database_specific":{"severity":"Low","cpes":["cpe:2.3:a:python:python:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/python/cpython/commit/42d754e34c06e57ad6b8e7f92f32af679912d8ab"},{"type":"WEB","url":"https://github.com/python/cpython/issues/141707"},{"type":"WEB","url":"https://github.com/python/cpython/pull/143934"},{"type":"WEB","url":"https://mail.python.org/archives/list/security-announce@python.org/thread/EOMI5I66ZMKQ2INNFT6T7IAIKUGPZYIE/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-13462"},{"type":"WEB","url":"https://github.com/python/cpython/commit/7ad3093d76a748af55bdb1d2e8aad3638163b017"},{"type":"WEB","url":"https://github.com/python/cpython/commit/ae99fe3a33b43e303a05f012815cef60b611a9c7"}],"affected":[{"package":{"name":"python","ecosystem":"Bitnami","purl":"pkg:bitnami/python"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.15.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/python/BIT-python-2025-13462.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/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"}]}],"schema_version":"1.7.5"}
