CVE-2023-2975  (opens in a new tab)
CWE-345  (opens in a new tab)

How to fix?

Upgrade openssl to version 3.0.10, 3.1.2 or higher.

Overview

Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in the AES-SIV cipher implementation in ciphers/cipher_aes_siv.c, which ignores empty associated data entries, making them unauthenticated.

Applications that use the AES-SIV algorithm and want to authenticate empty data entries as associated data can be misled by removing, adding or reordering such empty entries as these are ignored by the OpenSSL implementation.

NOTE: This issue does not affect non-empty associated data authentication and the maintainers are currently unaware of any applications that use empty associated data entries.
