It was discovered that Perl’s Safe module - a module to compile and execute code in restricted compartments - could be bypassed.
Please note that this update is known to break Petal, an XML-based templating engine (shipped with Debian 6.0/Squeeze in the package libpetal-perl, see bug #582805 for details). A fix is not yet available. If you use Petal, you might consider to put the previous Perl packages on hold.
