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//cmdline (or /proc//environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks).

Severity: MEDIUM (5.3) Vector: CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
