{"id":"BIT-python-min-2024-0397","summary":"Memory race condition in ssl.SSLContext certificate store methods","details":"A defect was discovered in the Python “ssl” module where there is a memory\nrace condition with the ssl.SSLContext methods “cert_store_stats()” and\n“get_ca_certs()”. The race condition can be triggered if the methods are\ncalled at the same time as certificates are loaded into the SSLContext,\nsuch as during the TLS handshake with a certificate directory configured.\nThis issue is fixed in CPython 3.10.14, 3.11.9, 3.12.3, and 3.13.0a5.","aliases":["BIT-libpython-2024-0397","BIT-python-2024-0397","CVE-2024-0397","PSF-2024-4"],"modified":"2025-11-06T13:25:46.476Z","published":"2025-01-17T15:06:36.200Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:python:python:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/06/17/2"},{"type":"WEB","url":"https://github.com/python/cpython/commit/01c37f1d0714f5822d34063ca7180b595abf589d"},{"type":"WEB","url":"https://github.com/python/cpython/commit/29c97287d205bf2f410f4895ebce3f43b5160524"},{"type":"WEB","url":"https://github.com/python/cpython/commit/37324b421b72b7bc9934e27aba85d48d4773002e"},{"type":"WEB","url":"https://github.com/python/cpython/commit/542f3272f56f31ed04e74c40635a913fbc12d286"},{"type":"WEB","url":"https://github.com/python/cpython/commit/b228655c227b2ca298a8ffac44d14ce3d22f6faa"},{"type":"WEB","url":"https://github.com/python/cpython/commit/bce693111bff906ccf9281c22371331aaff766ab"},{"type":"WEB","url":"https://github.com/python/cpython/issues/114572"},{"type":"WEB","url":"https://github.com/python/cpython/pull/114573"},{"type":"WEB","url":"https://mail.python.org/archives/list/security-announce@python.org/thread/BMAK5BCGKYWNJOACVUSLUF6SFGBIM4VP/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-0397"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20250411-0006/"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/12/msg00000.html"}],"affected":[{"package":{"name":"python-min","ecosystem":"Bitnami","purl":"pkg:bitnami/python-min"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.8.20"},{"introduced":"3.9.0"},{"fixed":"3.9.20"},{"introduced":"3.10.0"},{"fixed":"3.10.14"},{"introduced":"3.11.0"},{"fixed":"3.11.9"},{"introduced":"3.12.0"},{"fixed":"3.12.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/python-min/BIT-python-min-2024-0397.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}],"schema_version":"1.7.3"}
