3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly, there is a brief window where the SSLSocket instance will detect the socket as \"not connected\" and won't initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not be authenticated if the server-side TLS peer is expecting client certificate authentication, and is indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path requires that the connection be closed on initialization of the SSLSocket.)", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "fixed": [ "Ubuntu-18:alt-python36-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-debug-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-devel-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-libs-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-test-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-tkinter-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-tools-0:3.6.15-17.amd64" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els-alt-python/cve/CVE-2023-40217" }, { "category": "external", "summary": "https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html", "url": "https://lists.debian.org/debian-lts-announce/2023/09/msg00022.html" }, { "category": "external", "summary": "https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html", "url": "https://lists.debian.org/debian-lts-announce/2023/10/msg00017.html" }, { "category": "external", "summary": "https://mail.python.org/archives/list/security-announce%40python.org/thread/PEPLII27KYHLF4AK3ZQGKYNCRERG4YXY/", "url": "https://mail.python.org/archives/list/security-announce%40python.org/thread/PEPLII27KYHLF4AK3ZQGKYNCRERG4YXY/" }, { "category": "external", "summary": "https://security.netapp.com/advisory/ntap-20231006-0014/", "url": "https://security.netapp.com/advisory/ntap-20231006-0014/" }, { "category": "external", "summary": "https://www.python.org/dev/security/", "url": "https://www.python.org/dev/security/" }, { "category": "external", "summary": "https://lists.debian.org/debian-lts-announce/2024/11/msg00005.html", "url": "https://lists.debian.org/debian-lts-announce/2024/11/msg00005.html" }, { "category": "external", "summary": "https://lists.debian.org/debian-lts-announce/2024/12/msg00000.html", "url": "https://lists.debian.org/debian-lts-announce/2024/12/msg00000.html" } ], "release_date": "2023-08-25T01:15:00Z", "remediations": [ { "category": "vendor_fix", "date": "2025-10-13T14:50:02.251158Z", "details": "Details on how to apply the fix are available at: https://cve.tuxcare.com/els-alt-python/releases/CLSA-2025:1760366999", "product_ids": [ "Ubuntu-18:alt-python36-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-debug-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-devel-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-libs-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-test-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-tkinter-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-tools-0:3.6.15-17.amd64" ], "url": "https://cve.tuxcare.com/els-alt-python/releases/CLSA-2025:1760366999" } ], "scores": [ { "cvss_v3": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 5.3, "baseSeverity": "MEDIUM", "confidentialityImpact": "LOW", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N", "version": "3.1" }, "products": [ "Ubuntu-18:alt-python36-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-debug-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-devel-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-libs-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-test-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-tkinter-0:3.6.15-17.amd64", "Ubuntu-18:alt-python36-tools-0:3.6.15-17.amd64" ] } ], "threats": [ { "category": "impact", "details": "Moderate" } ] } ] }
