CVE-2018-1120 kernel: fuse-backed file mmap-ed onto process cmdline arguments causes denial of service
Last modified: 2018-08-28 18:42:37 EDT
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).
