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.","state":"PUBLIC","assigner":"secalert@redhat.com","published_at":"2018-06-13 20:29:00","updated_at":"2020-06-30 16:15:00"},"problem_types":["CWE-362"],"metrics":[],"references":[{"url":"https://www.qualys.com/2018/05/17/procps-ng-audit-report-advisory.txt","name":"https://www.qualys.com/2018/05/17/procps-ng-audit-report-advisory.txt","refsource":"MISC","tags":["Exploit","Third Party Advisory"],"title":"","mime":"text/plain","httpstatus":"200","archivestatus":"200"},{"url":"http://www.securityfocus.com/bid/104214","name":"104214","refsource":"BID","tags":["Third Party Advisory","VDB Entry"],"title":"Procps-ng Procps Multiple Security Vulnerabilities","mime":"text/html","httpstatus":"200","archivestatus":"0"},{"url":"http://seclists.org/oss-sec/2018/q2/122","name":"[oss-security] 20180517 Qualys Security Advisory - Procps-ng Audit Report","refsource":"MLIST","tags":["Exploit","Mailing List","Third Party Advisory"],"title":"oss-sec: Qualys Security Advisory - Procps-ng Audit Report","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1121","name":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1121","refsource":"CONFIRM","tags":["Issue Tracking","Third Party Advisory"],"title":"Bug 1575473 – CVE-2018-1121 procps-ng, procps: process hiding through race condition enumerating /proc","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.exploit-db.com/exploits/44806/","name":"44806","refsource":"EXPLOIT-DB","tags":["Exploit","Third Party Advisory","VDB Entry"],"title":"Procps-ng - Multiple Vulnerabilities - Linux local Exploit","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2018-1121","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-1121","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2018","cve_id":"1121","vulnerable":"1","versionEndIncluding":"3.3.15","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"procps_project","cpe5":"procps","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2018-1121","ASSIGNER":"secalert@redhat.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"procps-ng, procps is vulnerable to a process hiding through race condition.
