[Pharo-project] Issue 3602 in pharo: Code evaluation possible in About box ...

Status: Accepted Owner: Torsten....(a)astares.de Labels: Milestone-1.3 New issue 3602 by Torsten....(a)astares.de: Code evaluation possible in About box ... http://code.google.com/p/pharo/issues/detail?id=3602 One can open the about box, select the word "LICENSE" and hit Cmd+D (which is a "do it"). => gives an error that this class is missing This could also make it possible to "break into" a deployed image that uses the about box for own purposes since one can select "define new class" from the menu then and in the next page (where one typically edits the class creation message one can enter any expression like "Browser open" or whatever).
