procps-ng before version 3.3.15 is vulnerable to a stack buffer overflow in pgrep. This vulnerability is mitigated by FORTIFY, as it involves strncat() to a stack-allocated string. When pgrep is compiled with FORTIFY , the impact is limited to a crash. https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-1125 https://security.archlinux.org/CVE-2018-1125 https://www.qualys.com/2018/05/17/procps-ng-audit-report-advisory.txt
