Allowing uncontrolled access to filesystem outside of the emulated DOS system seems to be a design decision for DOSBox, even though it may not be common for other emulators / virtualization solution. Given upstream statement mentioned in original report, this probably won't get changed soon. Andreas, have you possibly heard some other feedback from DOSBox community about this announcement?
No I have to. But from reading through the report this is nothing new imho. DOSBox has allowed this for a long time. The assessment of it being a potential risk is right _but_ it is not like a hidden magic feature but clear from design so I would say that this is nothing we have to worry about for now.
Given this is design decision and upstream does not seem to change this any time soon, I'm closing this as WONTFIX. If upstream decision is changed in the future, we will likely follow shortly after by moving to new upstream release, but it does not seem to make sense to do fork at the moment.
