      "value": "There is a potentially exploitable out of memory condition In Nanopb before 0.4.1, 0.3.9.5, and 0.2.9.4. When nanopb is compiled with PB_ENABLE_MALLOC, the message to be decoded contains a repeated string, bytes or message field and realloc() runs out of memory when expanding the array nanopb can end up calling `free()` on a pointer value that comes from uninitialized memory. Depending on platform this can result in a crash or further memory corruption, which may be exploitable in some cases. This problem is fixed in nanopb-0.4.1, nanopb-0.3.9.5, nanopb-0.2.9.4."

      "value": "Se presenta una condici\u00f3n de falta de memoria explotable potencialmente en Nanopb versiones anteriores a 0.4.1, 0.3.9.5 y 0.2.9.4. Cuando se compila nanopb con PB_ENABLE_MALLOC, el mensaje que va a ser decodificado contiene una cadena repetida, campo bytes o message y la funci\u00f3n realloc() se queda sin memoria cuando se expande la matriz, nanopb puede terminar llamando a \"free()\" en un valor de puntero que proviene de una memoria no inicializada. Dependiendo de la plataforma, esto puede resultar en un bloqueo o una mayor corrupci\u00f3n de la memoria, que puede ser explotable en algunos casos. Este problema es corregido en las versiones nanopb-0.4.1, nanopb-0.3.9.5, nanopb-0.2.9.4."
