AEADs/ascon-aead: Plaintext exposed in decrypt_in_place_detached even on tag verification failure
Summary
AEADs/ascon-aead: Plaintext exposed in decrypt_in_place_detached even on tag verification failure
Original description
The description as published by the source.
aes-gcm is a pure Rust implementation of the AES-GCM. In decrypt_in_place_detached, the decrypted ciphertext (which is the correct ciphertext) is exposed even if the tag is incorrect. This is because in decrypt_inplace in asconcore.rs, tag verification causes an error to be returned with the plaintext contents still in buffer. The vulnerability is fixed in 0.4.3.
