Debian DLA-1593-1 : phpbb3 security update

High Nessus Plugin ID 119121


The remote Debian host is missing a security update.


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.


Upgrade the affected phpbb3, and phpbb3-l10n packages.
