CVE-2018-1124: Canonical Ubuntu Linux

High severity, CVSS 7.8. EPSS: 1.9% chance of exploitation in the next 30 days.

procps-ng before version 3.3.15 is vulnerable to multiple integer overflows leading to a heap corruption in file2strvec function. This allows a privilege escalation for a local attacker who can create entries in procfs by starting processes, which could result in crashes or arbitrary code execution in proc utilities run by other users.
