An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0. In
some configurations, an unauthenticated attacker can send an invalid
ClientHello message to a DTLS server that causes a heap-based buffer
over-read of up to 255 bytes. This can cause a server crash or possibly
information disclosure based on error responses. Affected configurations
have MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE enabled and
MBEDTLS_SSL_IN_CONTENT_LEN less than a threshold that depends on the
configuration: 258 bytes if using mbedtls_ssl_cookie_check, and possibly up
to 571 bytes with a custom cookie check function.
