None of the other packages is affected by this, so there is no need for an update. Nevertheless we will release an update, but there is no need to hurry and realease something untested which may harm more then it helps! The reason is very simple:
magic_quotes_gpc is always off in the php.ini in ispconfig. This is the case for all packages incl. ispconfig. The bug appears only if magic_quotes_gpc is set to on, but thats not the case so neither ISPConfig nor one of the other packages are affected by this bug.
