phpBB Group Announcement

Detail
====== 

Below is an announcement received by UNIRAS from phpBB, that includes details of a
vulnerability that can be patched.  UNIRAS believes the vulnerability may allow a
remote attacker to execute arbitrary code on a system. 

======

Hi everyone,
phpBB Group announces the release of phpBB 2.0.16. This release addresses some 
bugfixes and one critical security issue. To fix this, please apply the following change:
In viewtopic.php
Find:
$message = str_replace('"', '"', substr(@preg_replace('#(>(((?>([^><]+|(?R)))*)<))#se', 
"@preg_replace('#b(" . str_replace('\', '\\', $highlight_match) . ")b#i', 
'<span style="color:#" . $theme['fontcolor3'] . ""><b>\\1</b></span>', '\0')", 
'>' . $message . '<'), 1, -1));
Replace with:
$message = str_replace('"', '"', substr(@preg_replace('#(>(((?>([^><]+|(?R)))*)<))#se', 
"@preg_replace('#b(" . str_replace('\', '\\', addslashes($highlight_match)) . ")b#i', 
'<span style="color:#" . $theme['fontcolor3'] . ""><b>\\1</b></span>', 
'\0')", '>' . $message . '<'), 1, -1));
If your mail program wraps the lines it is advised to get the fix from the official 
announcement at: http://www.phpbb.com/phpBB/viewtopic.php?t=302011

We urge you to update as soon as possible. You can of course find this 
download available on our downloads page (http://www.phpbb.com/downloads.php). 
As per usual three packages are available to simplify your update.
The Full Package contains entire phpBB2 source and English language package.
The Changed Files Only contains only those files changed from previous versions 
of phpBB. Please note this archive contains changed files for each previous release.
Patch Files contains patch compatible patches from the previous versions of phpBB.
Select whichever package is most suitable for you. 
The changelog (contained within this release) is as follows:
- - Fixed critical issue with highlighting - Discovered and fix provided by Ron van Daal
- - Url descriptions able to be wrapped over more than one line again
- - Fixed bug with eAccelerator in admin_ug_auth.php
- - Check new_forum_id for existence in modcp.php - alessnet
- - Prevent uploading avatars with no dimensions - Xpert
- - Fixed bug in usercp_register.php, forcing avatar file removal without updating 
avatar informations within the database - HenkPoley
- - Fixed bug in admin re-authentication redirect for servers not having index.php 
as one of their default files set
As always, our Code Changes Tutorial is available too for those with heavily 
modded boards.
It can be downloaded from http://www.phpbb.com/phpBB/viewtopic.php?t=301712
