CVE-2018-10545  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade php to version 5.6.35, 7.0.29, 7.1.16, 7.2.4 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. An issue was discovered in PHP before 5.6.35, 7.0.x before 7.0.29, 7.1.x before 7.1.16, and 7.2.x before 7.2.4. Dumpable FPM child processes allow bypassing opcache access controls because fpm_unix.c makes a PR_SET_DUMPABLE prctl call, allowing one user (in a multiuser environment) to obtain sensitive information from the process memory of a second user's PHP applications by running gcore on the PID of the PHP-FPM worker process.
