Starting in version 0.10.0 and prior to version 0.10.3, in the AES GCM implementation of decrypt_in_place_detached, the decrypted ciphertext (i.e. the correct plaintext) is exposed even if tag verification fails. If a program using the `aes-gcm` crate's `decrypt_in_place*` APIs accesses the buffer after decryption failure, it will contain a decryption of an unauthenticated input. Depending on the specific nature of the program this may enable Chosen Ciphertext Attacks (CCAs) which can cause a catastrophic breakage of the cipher including full plaintext recovery. Version 0.10.3 contains a fix for this issue.","state":0,"publishedAt":"2023-09-22T15:19:15.445+00:00","modifiedAt":"2025-06-18T14:22:56.534+00:00","affected":[{"ecosystem":"Vendor product","name":"AEADs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"RustCrypto\",\n                    \"product\": \"AEADs\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.10.0, < 0.10.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:H/A:N","score":4.7,"severity":"MEDIUM"}],"references":["https://github.com/RustCrypto/AEADs/security/advisories/GHSA-423w-p2w9-r7vq","https://docs.rs/aes-gcm/latest/src/aes_gcm/lib.rs.html#309","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/RYQCICN6BVC6I75O3F6W4VK4J3MOYDJU/","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U67ZSMNX5V3WTBYPUYF45PSFG4SF5SGF/","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ROBB6TBDAGEQ2WIINR34F3DPSN3FND6K/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-42811","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-42811","identifiers":["CVE-2023-42811"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
