CVE-2018-10545

Vulnerability Summary

An issue exists in PHP prior to 5.6.35, 7.0.x prior to 7.0.29, 7.1.x prior to 7.1.16, and 7.2.x prior to 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.
