CVE-2018-10545: Infoleak

First published: Thu Nov 30 2017(Updated: )

A flaw was found in PHP versions 5.6 and 7.x. After changing UID and GID, PHP-FPM sets pool worker processes to be dumpable. This allows a local user with the same UID and GID to attach to the PHP-FPM workers and gain access to any restricted resources that are not supposed to be allowed. As a result sensitive configuration data for other accounts can be accessed directly in the PHP worker process's memory.
