Title: use of Ux in ubuntu-* abstractions and profiles is too lenient and should be improved Status in “apparmor” package in Ubuntu: In Progress Status in “cups” package in Ubuntu: Triaged Status in “evince” package in Ubuntu: In Progress Status in “firefox” package in Ubuntu: Triaged Status in “apparmor” source package in Oneiric: In Progress Status in “cups” source package in Oneiric: Won't Fix Status in “evince” source package in Oneiric: In Progress Status in “firefox” source package in Oneiric: Triaged Bug description: Ux clears potentially harmful environment variables such as LD_PRELOAD and LD_LIBRARY_PATH (and others). Because it doesn't clear out all variables that can influence child processes, the confined parent process may have too much influence over the child. When considering GUI applications such as those based on gtk, child processes can also be called with --gtk-module. Since there are several applications in the ubuntu-specific abstractions that can be affected in this manner, evince, firefox, the chromium profile as included in apparmor-profiles and the ubuntu- specific abstractions themselves should be adjusted to address this issue. Cups is also affected because of its use of Ux with filters, however it runs these filters as non-root and the environment under which these filters is run is more tightly controlled. Cups should be investigated more and we should consider confining (at least) those filters that we ship in Ubuntu.
