This security bulletin contains information about 2 secuirty vulnerabilities.


1) Cryptographic issues (CVE-ID: CVE-2024-1543)

A side channel vulnerability with AES T-Tables is possible in a very controlled environment where precision sub-cache-line inspection can happen, such as inside an Intel SGX enclave. This can lead to recovery of the AES key. To prevent this type of attack, wolfSSL added an AES bitsliced implementation which can be enabled with the "--enable-aes-bitsliced" configure option.


2) Improper restriction of software interfaces to hardware features (CVE-ID: CVE-2024-1545)

The vulnerability allows a remote attacker to decrypt data.

The vulnerability exists due to a fault injection within the RsaPrivateDecryption() function in wolfssl/wolfcrypt/src/rsa.c. A local user can perform perform a Rowhammer fault injection and gain access to sensitive information.
