Synopsis
========

A vulnerability was discovered in PHPUnit which may allow an
unauthenticated remote attacker to execute arbitrary PHP code.

Background
==========

PHPUnit is a programmer-oriented testing framework for PHP. It is an
instance of the xUnit architecture for unit testing frameworks.

Affected packages
=================

    ——————————————————————-
     Package              /     Vulnerable     /            Unaffected
    ——————————————————————-
  1  dev-php/phpunit            < 5.7.15-r1              >= 5.7.15-r1 

Description
===========

When PHPUnit is installed in a production environment via composer and
these modules are in a web accessible directory, the eval-stdin.php
file in PHPUnit contains vulnerable statements that trigger the
vulnerability.

Impact
======

A remote attacker could possibly execute arbitrary PHP code or cause a
Denial of Service condition.

Workaround
==========

There are several ways to fix or mitigate this vulnerability:

Remove PHPUnit from the production environment.

Update PHPUnit.

Manually apply the patch.

Disable direct access to the composer packages by placing .htaccess
file to /vendor folder.

Resolution
==========

All PHPUnit users should upgrade to the latest version:

  # emerge –sync
  # emerge –ask –oneshot –verbose “>=dev-php/phpunit-5.7.15-r1”
