CVE-2018-1125: Canonical Ubuntu Linux

High severity, CVSS 7.5. EPSS: 1.9% chance of exploitation in the next 30 days.

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 (as on Red Hat Enterprise Linux and Fedora), the impact is limited to a crash.

Affected products

• Canonical Ubuntu Linux: version 12.04 only; version 14.04 only; version 16.04 only; version 17.10 only; version 18.04 only
• Debian Debian Linux: version 7.0 only; version 8.0 only; version 9.0 only
• Opensuse Leap: version 15.1 only
• Procps-NG Project Procps-NG: before 3.3.15 (fixed in 3.3.15)
