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.

Affected configurations

• php php (< 5.6.35) • php php (>= 7.0.0 < 7.0.29) • php php (>= 7.1.0 < 7.1.16) • php php (>= 7.2.0 < 7.2.4) • canonical ubuntu linux 12.04 • canonical ubuntu linux 14.04 • canonical ubuntu linux 16.04 • canonical ubuntu linux 17.10 • canonical ubuntu linux 18.04 • debian debian linux 7.0 • debian debian linux 8.0 • debian debian linux 9.0 • netapp storage automation store
