Debian DLA-1593-1 : phpbb3 security update
Medium Nessus Plugin ID 119121
SynopsisThe remote Debian host is missing a security update.
DescriptionSimon 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
For Debian 8 'Jessie', this problem has been fixed in version
We recommend that you upgrade your phpbb3 packages.

to automatically clean and format it as much as possible without
introducing additional issues.
