PHP is an open source general-purpose scripting language that is especially suited for web development.
A underflow in env_path_info in PHP-FPM under certain configurations can be exploited to gain remote code execution.
A remote attacker, by sending special crafted HTTP requests, could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.
If patching is not feasible, the suggested workaround is to include checks to verify whether or not a file exists before passing to PHP.
All PHP 5.6 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.6.40-r7"
