{"id":"OESA-2025-2637","summary":"python3 security update","details":"Security Fix(es):\n\nCPython 3.9 and earlier doesn't disallow configuring an empty list ("[]") for SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API. This results in a buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically a protocol name would be configured).(CVE-2024-5642)","modified":"2026-08-18T01:19:19.596227594Z","published":"2025-11-07T11:09:45Z","upstream":["CVE-2024-5642"],"database_specific":{"severity":"Medium"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2025-2637"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-5642"}],"affected":[{"package":{"name":"python3","ecosystem":"openEuler:22.03-LTS-SP3","purl":"pkg:rpm/openEuler/python3&distro=openEuler-22.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.9-44.oe2203sp3"}]}],"ecosystem_specific":{"aarch64":["python3-3.9.9-44.oe2203sp3.aarch64.rpm","python3-debug-3.9.9-44.oe2203sp3.aarch64.rpm","python3-debuginfo-3.9.9-44.oe2203sp3.aarch64.rpm","python3-debugsource-3.9.9-44.oe2203sp3.aarch64.rpm","python3-devel-3.9.9-44.oe2203sp3.aarch64.rpm","python3-unversioned-command-3.9.9-44.oe2203sp3.aarch64.rpm"],"noarch":["python3-help-3.9.9-44.oe2203sp3.noarch.rpm"],"src":["python3-3.9.9-44.oe2203sp3.src.rpm"],"x86_64":["python3-3.9.9-44.oe2203sp3.x86_64.rpm","python3-debug-3.9.9-44.oe2203sp3.x86_64.rpm","python3-debuginfo-3.9.9-44.oe2203sp3.x86_64.rpm","python3-debugsource-3.9.9-44.oe2203sp3.x86_64.rpm","python3-devel-3.9.9-44.oe2203sp3.x86_64.rpm","python3-unversioned-command-3.9.9-44.oe2203sp3.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2025-2637.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L"}]}
