      "value": "An off-by-one heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a message bigger than INT_MAX bytes, leading to an incorrect calculation of the buffer size to store the message, resulting in an application crash. This issue affects glibc 2.37 and newer."

Esta funci\u00f3n es llamada por las funciones syslog y vsyslog. Este problema ocurre cuando estas funciones se llaman con un mensaje mayor que INT_MAX bytes, lo que genera un c\u00e1lculo incorrecto del tama\u00f1o del b\u00fafer para almacenar el mensaje, lo que provoca un bloqueo de la aplicaci\u00f3n. Este problema afecta a glibc 2.37 y posteriores."
