"Simon Scannell and Robin Peraglie of RIPS Technologies discovered that
passing an absolute path to a file_exists check in phpBB, a full
featured web forum, allows remote code execution through Object
Injection by employing Phar deserialization when an attacker has
access to the Admin Control Panel with founder permissions.

The fix for this issue resulted in the removal of setting the
ImageMagick path. The GD image library can be used as a replacement
and a new event to generate thumbnails was added, so it is possible to
write an extension that uses a different image library to generate
thumbnails.

For Debian 8 'Jessie', this problem has been fixed in version
3.0.12-5+deb8u2.

We recommend that you upgrade your phpbb3 packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
