Instances are vulnerable depending on the web server configuration, in
particular PATH_INFO handling. For a full list of preconditions,
check: https://github.com/neex/phuip-fpizdam

For Debian 8 'Jessie', this problem has been fixed in version
5.6.40+dfsg-0+deb8u7.

We recommend that you upgrade your php5 packages.
