In affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as `bytes`) to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-754"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2023-23931", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 6.5, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L", "integrityImpact": "LOW", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "LOW", "privilegesRequired": "NONE", "confidentialityImpact": "NONE"}, "impactScore": 2.5, "exploitabilityScore": 3.9}}, "publishedDate": "2023-02-07T21:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:cryptography_project:cryptography:*:*:*:*:*:python:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "39.0.1", "versionStartIncluding": "1.8"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2023-02-16T16:57Z"}
