CVE-2018-1122

Published: 17 May 2018

procps-ng before version 3.3.15 is vulnerable to a local privilege escalation in top. If a user runs top with HOME unset in an attacker-controlled directory, the attacker could achieve privilege escalation by exploiting one of several vulnerabilities in the config_file() function.
