CVE-2024-28755 Information

Description

An issue was discovered in Mbed TLS 3.5.x before 3.6.0. When an SSL context was reset with the mbedtls_ssl_session_reset() API the maximum TLS version to be negotiated was not restored to the configured one. An attacker was able to prevent an Mbed TLS server from establishing any TLS 1.3 connection potentially resulting in a Denial of Service or forced version downgrade from TLS 1.3 to TLS 1.2.
