| Title | Potential Plaintext Exposure from Forged Tag in Mirage-Crypto AES/GCM and ChaCha20 Decrypt Functions |
Wed, 09 Sep 2026 04:30:00 +0000
| Type | Values Removed | Values Added |
|---|---|---|
| Description | An issue was discovered in the mirage-crypto package before 2.2.0 for OCaml. The AES.GCM.authenticate_decrypt_into and Chacha20.authenticate_decrypt_into functions write the decrypted plaintext into a caller-provided buffer and only then compares the tag. On a forged tag, the functions returns false, but the destination buffer already holds the full plaintext. | |
