CVE-2023-42811 – AEADs/aes-gcm: Plaintext exposed in decrypt_in_place_detached even on tag verification failure

https://notcve.org/view.php?id=CVE-2023-42811

22 Sep 2023 — aes-gcm is a pure Rust implementation of the AES-GCM. 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 Ciph... • https://docs.rs/aes-gcm/latest/src/aes_gcm/lib.rs.html#309 • CWE-347: Improper Verification of Cryptographic Signature •
