    {
      "lang": "en",
      "value": "An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftp_input() function and could occur while processing a udp packet that is smaller than the size of the 'tftp_t' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0."

      "value": "Se ha encontrado un problema de inicializaci\u00f3n de puntero no v\u00e1lido en la implementaci\u00f3n de redes SLiRP de QEMU. El fallo se presenta en la funci\u00f3n tftp_input() y podr\u00eda ocurrir mientras se  procesa un paquete udp m\u00e1s peque\u00f1o que el tama\u00f1o de la estructura \"tftp_t\". Este problema puede conllevar a un acceso de lectura fuera de l\u00edmites o a una divulgaci\u00f3n indirecta de la memoria del host al invitado. La mayor amenaza de esta vulnerabilidad es la confidencialidad de los datos. Este fallo afecta a libslirp versiones anteriores a 4.6.0"
