The following updates has been released for Debian GNU/Linux:

Debian GNU/Linux 8 LTS:
DLA 1593-1: phpbb3 security update
DLA 1594-1: xml-security-c security update

Debian GNU/Linux 9:
DSA 4344-1: roundcube security update

DLA 1593-1: phpbb3 security update

Package : phpbb3
Version : 3.0.12-5+deb8u2
CVE ID : CVE-2018-19274

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.
