Description

The remote host is affected by the vulnerability described in GLSA-200804-19 (PHP Toolkit: Data disclosure and Denial of Service)

Toni Arnold, David Sveningsson, Michal Bartoszkiewicz, and Joseph
reported that php-select does not quote parameters passed to the 'tr'
command, which could convert the '-D PHP5' argument in the
'APACHE2_OPTS' setting in the file /etc/conf.d/apache2 to lower case.

Impact :

An attacker could entice a system administrator to run 'emerge
php' or call 'php-select -t apache2 php5' directly in a
directory containing a lower case single-character named file, which
would prevent Apache from loading mod_php and thereby disclose PHP
source code and cause a Denial of Service.

Workaround :

Do not run 'emerge' or 'php-select' from a working directory which
contains a lower case single-character named file.
