## Description

The Safe (aka Safe.pm) module before 2.25 for Perl allows context-dependent
attackers to bypass intended (1) Safe::reval and (2) Safe::rdo access
restrictions, and inject and execute arbitrary code, via vectors involving
implicitly called methods and implicitly blessed objects, as demonstrated
by the (a) DESTROY and (b) AUTOLOAD methods, related to "automagic
methods."
