CVE-2018-10545

php: Dumpable FPM child processes allow bypassing opcache access controls

Published Apr 29, 2018 CVSS 3.0 · 4.7 Medium EPSS < 1% KEV · Not listed
Description
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.
