Description Vincent Danen 2010-12-17 23:36:20 UTC

Sebastian Krahmer reported that the udisks service (via D-BUS) could be used to load arbitrary Linux kernel modules.  Since "mount -t $NAME" is called, this also triggers a "modprobe -q -- $NAME" which will load the Linux kernel module from /lib/modules/.

The upstream bug report is: https://bugs.freedesktop.org/show_bug.cgi?id=32232 and no upstream fix has been made as of yet, although the upstream bug report has a few suggestions on how to correct this.

Comment 6 Vincent Danen 2011-01-31 19:21:20 UTC

This issue can only be exploited by users who are logged in locally and in an active session.  Attempting the same via remote (i.e. via ssh) fails with:

Error org.freedesktop.UDisks.Error.PermissionDenied: Not Authorized

Comment 10 Vincent Danen 2011-02-23 17:45:06 UTC

Statement:

The Red Hat Security Response Team has rated this issue as having low security impact, a future update to Red Hat Enterprise Linux 6 may address this flaw.  This issue did not affect Red Hat Enterprise Linux 4 or 5.

Comment 11 Vincent Danen 2012-08-16 18:05:14 UTC

Upstream patch:

http://cgit.freedesktop.org/udisks/commit/?id=c933a929f07421ec747cebb24d5e620fc2b97037

And fixed in upstream 1.0.3.  Current Fedora releases have 1.0.4 so they have been addressed.
