"value": "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."

"value": "Se ha descubierto un problema en Mbed TLS antes de la versi\u00f3n 2.28.1 y 3.x antes de la 3.2.0. En algunas configuraciones, un atacante no autenticado puede enviar un mensaje ClientHello no v\u00e1lido a un servidor DTLS que provoca una sobrelectura del b\u00fafer basada en el mont\u00f3n de hasta 255 bytes. Esto puede causar una ca\u00edda del servidor o posiblemente la divulgaci\u00f3n de informaci\u00f3n basada en las respuestas de error. Las configuraciones afectadas tienen MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE habilitado y MBEDTLS_SSL_IN_CONTENT_LEN menos que un umbral que depende de la configuraci\u00f3n: 258 bytes si se utiliza mbedtls_ssl_cookie_check, y posiblemente hasta 571 bytes con una funci\u00f3n de comprobaci\u00f3n de cookies personalizada"
