Subject: CVE Request: policykit (minor)

Hi,

Dan Rosenberg found[1] a minor information disclosure vulnerability
in pkexec, which has been fixed[2] upstream.  It would disclose the
existence of files a given user would normally not be able to confirm:

$ pkexec /home/drosenbe/secret/hidden
(password prompt)
$ pkexec /home/drosenbe/secret/doesnotexist
Error getting information about /home/drosenbe/secret/doesnotexist: No such file or directory

Thanks,

-Kees
