I have in the user home a file like "watermark.png", I can generate a thumbnail by using an URL like :

/createthumb.php?filename=../watermark.png&size=320

Even something like this works:

/createthumb.php?filename=../../../usr/share/pixmaps/debian-logo.png&size=320

Even if it would not render anything other than an image type this seems to be a security issue.

remove minigalnano role (unmaintained, security issues: sebsauvage/Mi…

…nigalNano#123)

minigalnano must be removed manually if installed:
rm -r /etc/rsnapshot.d/minigalnano.conf /var/lib/srv01/minigalnano-installed /var/www/images/ /etc/apache2/conf-available/minigalnano-password.conf
owncloud gallery + sharing directory via URL is the new image sharing solution
