Synopsis
========
phpBB is vulnerable to a cross-site scripting attack that could allow
arbitrary scripting code execution.
Background
==========
phpBB is an Open Source bulletin board package.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/phpBB < 2.0.15 >= 2.0.15
Description

improper sanitization of user supplied input. Coupled with poor
validation of BBCode URLs which may be included in a forum post, an
unsuspecting user may follow a posted link triggering the
vulnerability.
Impact

Successful exploitation of the vulnerability could cause arbitrary
scripting code to be executed in the browser of a user.
Workaround

emerge --sync
emerge --ask --oneshot --verbose ">=www-apps/phpbb-2.0.15"
