Description Miloslav Trmač 2011-03-03 13:57:06 UTC

Please implement a system-wide option that could enforce using the "noexec" option on all mounts by unprivileged users.

On desktop systems, the "noexec" option can protect users against mistakenly running applications.

On high-security systems, system policy may forbid running binaries that were not installed by the system administrator, and such policies are required by some industry standards.  On systems with such policies, /tmp and /home may be also mounted "noexec", or an auditing mechanism can be used to watch violations of this policy; the ability of an user to mount an external volume that contains executables would bypass these measures.

Currently the only option seems to be configuring PolicyKit to completely forbid mounting of removable media by unprivileged users, which results in a significant loss of functionality.
