Descriptions

In MatrixSSL 3.8.3 Open through 4.2.1 Open, the DTLS server mishandles incoming network messages leading to a heap-based buffer overflow of up to 256 bytes and possible Remote Code Execution in parseSSLHandshake in sslDecode.c. During processing of a crafted packet, the server mishandles the fragment length value provided in the DTLS message.

En MatrixSSL versiones 3.8.3 Open hasta 4.2.1 Open, el servidor DTLS maneja inapropiadamente los mensajes de red entrantes que conllevan a un desbordamiento del búfer en la región heap de la memoria de hasta 256 bytes y la posible ejecución de código remota en la función parseSSLHandshake en el archivo sslDecode.c. Durante el procesamiento de un paquete diseñado, el servidor maneja inapropiadamente el valor de longitud del fragmento proporcionado en el mensaje DTLS.
