{"id":"PSF-2026-10","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":["CVE-2025-13462"],"modified":"2026-05-02T00:45:33.012403Z","published":"2026-03-12T17:59:26.620Z","database_specific":{"cwe_ids":[]},"references":[{"type":"WEB","url":"https://github.com/python/cpython/pull/143934"},{"type":"REPORT","url":"https://github.com/python/cpython/issues/141707"},{"type":"ADVISORY","url":"https://mail.python.org/archives/list/security-announce@python.org/thread/EOMI5I66ZMKQ2INNFT6T7IAIKUGPZYIE/"},{"type":"FIX","url":"https://github.com/python/cpython/commit/42d754e34c06e57ad6b8e7f92f32af679912d8ab"},{"type":"FIX","url":"https://github.com/python/cpython/commit/7ad3093d76a748af55bdb1d2e8aad3638163b017"},{"type":"FIX","url":"https://github.com/python/cpython/commit/ae99fe3a33b43e303a05f012815cef60b611a9c7"},{"type":"FIX","url":"https://github.com/python/cpython/commit/72dde1016493c52abe857fc4a7bf6c40138b4114"},{"type":"FIX","url":"https://github.com/python/cpython/commit/9a23b753552afa28e3a2f4d8863572fc66479406"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/python/cpython","events":[{"introduced":"0"},{"fixed":"42d754e34c06e57ad6b8e7f92f32af679912d8ab"},{"fixed":"7ad3093d76a748af55bdb1d2e8aad3638163b017"},{"fixed":"ae99fe3a33b43e303a05f012815cef60b611a9c7"},{"fixed":"72dde1016493c52abe857fc4a7bf6c40138b4114"},{"fixed":"9a23b753552afa28e3a2f4d8863572fc66479406"}]}],"versions":["v0.9.8","v0.9.9","v1.0.1","v1.0.2","v1.1","v1.1.1","v1.2","v1.2b1","v1.2b2","v1.2b3","v1.2b4","v1.3","v1.3b1","v1.4","v1.4b1","v1.4b2","v1.4b3","v1.5","v1.5.1","v1.5.2","v1.5.2a1","v1.5.2a2","v1.5.2b1","v1.5.2b2","v1.5.2c1","v1.5a1","v1.5a2","v1.5a3","v1.5a4","v1.5b1","v1.5b2","v1.6a1","v1.6a2","v2.0","v2.0b1","v2.0b2","v2.0c1","v2.1","v2.1a1","v2.1a2","v2.1b1","v2.1b2","v2.1c1","v2.1c2","v2.2a3","v2.3c1","v2.3c2","v2.4","v2.4a1","v2.4a2","v2.4a3","v2.4b1","v2.4b2","v2.4c1","v3.0a1","v3.0a2","v3.0a3","v3.0a4","v3.0a5","v3.0b1","v3.0b2","v3.0b3","v3.0rc1","v3.0rc2","v3.0rc3","v3.1","v3.10.0a1","v3.10.0a7","v3.10.0b1","v3.10.0b2","v3.10.0b3","v3.10.0b4","v3.10.0rc1","v3.10.0rc2","v3.10.1","v3.10.10","v3.10.11","v3.10.12","v3.10.13","v3.10.14","v3.10.15","v3.10.16","v3.10.17","v3.10.18","v3.10.19","v3.10.2","v3.10.20","v3.10.3","v3.10.4","v3.10.5","v3.10.6","v3.10.7","v3.10.8","v3.10.9","v3.11.0a3","v3.11.0a4","v3.11.0a5","v3.11.0a6","v3.11.0a7","v3.11.0b1","v3.11.0b2","v3.11.0b3","v3.11.0b4","v3.11.0b5","v3.11.0rc1","v3.11.0rc2","v3.11.1","v3.11.10","v3.11.11","v3.11.12","v3.11.13","v3.11.14","v3.11.15","v3.11.2","v3.11.3","v3.11.4","v3.11.5","v3.11.6","v3.11.7","v3.11.8","v3.11.9","v3.12.0a1","v3.12.0a2","v3.12.0a3","v3.12.0a4","v3.12.0a5","v3.12.0a6","v3.12.0a7","v3.12.0b1","v3.13.0","v3.13.0a1","v3.13.0a2","v3.13.0a3","v3.13.0a4","v3.13.0a5","v3.13.0a6","v3.13.0b1","v3.13.0b2","v3.13.0b3","v3.13.0b4","v3.13.0rc1","v3.13.0rc2","v3.13.0rc3","v3.13.1","v3.13.10","v3.13.11","v3.13.12","v3.13.2","v3.13.3","v3.13.4","v3.13.5","v3.13.6","v3.13.7","v3.13.8","v3.14.0","v3.14.0a1","v3.14.0a2","v3.14.0a3","v3.14.0a4","v3.14.0a5","v3.14.0a6","v3.14.0a7","v3.14.0b1","v3.14.0b2","v3.14.0b3","v3.14.0b4","v3.14.0rc1","v3.14.0rc2","v3.14.0rc3","v3.14.1","v3.14.2","v3.14.3","v3.15.0a1","v3.15.0a2","v3.15.0a3","v3.15.0a4","v3.15.0a5","v3.15.0a6","v3.15.0a7","v3.1a1","v3.1a2","v3.1b1","v3.1rc1","v3.1rc2","v3.2a1","v3.2a2","v3.2a3","v3.2a4","v3.2b1","v3.2b2","v3.2rc1","v3.2rc2","v3.2rc3","v3.3.0a2","v3.3.0a3","v3.3.0a4","v3.3.0b1","v3.3.0b2","v3.3.0rc1","v3.3.0rc2","v3.3.0rc3","v3.4.0a1","v3.4.0a2","v3.4.0a3","v3.4.0a4","v3.4.0b1","v3.4.0b2","v3.4.0b3","v3.5.0a1","v3.5.0a2","v3.5.0a3","v3.5.0a4","v3.5.0b1","v3.6.0a3","v3.6.0b1","v3.7.0a2","v3.9.0a2"],"database_specific":{"source":"https://github.com/psf/advisory-database/blob/main/advisories/python/PSF-2026-10.json"}}],"schema_version":"1.7.5"}
