Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Cryptographic issues

EUVDB-ID: #VU84842

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-1543

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

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.

Mitigation

Install updates from vendor's repository.
