"value": "A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks)."

Al realizar un mmap() sobre un archivo copiado con FUSE en la memoria de un proceso que contiene argumentos de l\u00ednea de comandos (o cadenas de entorno), un atacante puede hacer que las utilidades de psutils o procps (como ps o w) o cualquier otro programa que realiza una llamada read() a los archivos /proc//cmdline (o /proc//environ) se bloqueen indefinidamente (denegaci\u00f3n de servicio) o durante un tiempo determinado (como primitiva de sincronizaci\u00f3n para otros ataques)."
