Created sudo tracking bugs for this issue: Affects: fedora-all [bug 1277427] Upstream patch: http://www.sudo.ws/repos/sudo/rev/9636fd256325 sudo-1.8.15-1.fc23 has been pushed to the Fedora 23 stable repository. If problems still persist, please make note of it in this bug report. sudo-1.8.15-1.fc22 has been pushed to the Fedora 22 stable repository. If problems still persist, please make note of it in this bug report. Configurations like the one mentioned in comment #0, where a user has edit or execute privileges for files in a directory writeable by the user, are inherently dangerous. It's (almost?) impossible to make such scenarios entirely secure and controllable. Even with the upstream patch, which disables following symlinks by default, there is no full protection. I can only recommend to migrate to a more secure configuration. Upstream bug report for this issue: https://bugzilla.sudo.ws/show_bug.cgi?id=707 It notes that the fix in 1.8.15 does not completely address the issue. Following additional changes were applied post 1.8.16: https://www.sudo.ws/repos/sudo/rev/33272418bb10 https://www.sudo.ws/repos/sudo/rev/c2e36a80a279 And also related: https://www.sudo.ws/repos/sudo/rev/b41c5b289f35 https://www.sudo.ws/repos/sudo/rev/574e4a840879 https://www.sudo.ws/repos/sudo/rev/3f559a389bf9 https://www.sudo.ws/repos/sudo/rev/fe50d0c1f1b9 |
