Package: kobodeluxe Version: 0.5.1-11 Severity: wishlist User: [email protected] Usertags: setgid
The /usr/games/kobodl executable is setgid games. Because this game depends on libraries that make no attempt to avoid privilege escalation from the caller to the games group, this use of setgid is basically security theatre: it's essentially equivalent to making the high scores world-writeable. In particular, because this game depends on SDL, it's very easy to use it to escalate privileges to the games group. SDL is not designed to be used by set*id executables (reference: https://github.com/libsdl-org/SDL/issues/14717). Discussion on the debian-devel-games list starting at https://lists.debian.org/debian-devel-games/2025/12/msg00016.html (or equivalently https://lists.debian.org/msgid-search/[email protected]) indicates that several games team members think the complexity cost and security implications of games being setgid are too high a price to pay for a shared high-score table on multi-user systems. Could this game be modified to save high-scores to a per-user location instead? In SDL 2, the SDL_PrefPath() is likely to be the most suitable place. Unfortunately SDL 1.2 does not provide that function, but it could be copied or reimplemented if necessary. Thanks, smcv
