CVE-2018-1120

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).
