CVE-2018-1121 (GCVE-0-2018-1121)

Vulnerability from cvelistv5

Published

2018-06-13 20:00

Modified

2024-08-05 03:51

Severity ?

3.9 (Low) - CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L

CWE

CWE-367

Summary

procps-ng, procps is vulnerable to a process hiding through race condition. Since the kernel's proc_pid_readdir() returns PID entries in ascending numeric order, a process occupying a high PID can use inotify events to determine when the process list is being scanned, and fork/exec to obtain a lower PID, thus avoiding enumeration. An unprivileged attacker can hide a process from procps-ng's utilities by exploiting a race condition in reading /proc/PID entries. This vulnerability affects procps and procps-ng up to version 3.3.15, newer versions might be affected also.
