Descriptions
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).
Se ha encontrado un error que afecta al kernel de Linux en versiones anteriores a la 4.17. Al realizar un mmap() sobre un archivo copiado con FUSE en la memoria de un proceso que contiene argumentos de línea 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 (denegación de servicio) o durante un tiempo determinado (como primitiva de sincronización para otros ataques).
