Package: udev
Version: 164-3
Severity: normal

Hi,

udev contains support for consolekit. The rule file 70-acl.rules and 
/lib/udev/udev-acls change the ACLs of certain device files to give local users
access. 

I consider this a serious security problem. I have a guest account to let others
use my system. When they log in, they automatically gain access to these
devices. And they can keep this access even after logout, if they so wish, by 
starting a background job that keeps the device open. Think: camera and 
microphone.

Consolekit is broken by design and there is no way of fixing these security 
implications. The only real fix is, to not use consolekit, and stick with the 
traditional scheme of letting root decide who gets permissions for what. 
Consolekit takes away this control from root. In my opinion, root should always
be in full control.

I'd suggest to move 70-acl.rules to the consolekit package and remove the 
dependency to consolekit. This way, nothing changes for folks who value 
convenience over everything else. But those who value security and like
to be in full control over their own system, would no longer be forced to use
consolekit. In any case, it seems more logical to me, that consolekit specifica
should be contained in the consolekit package.

Cheers,
harry
