Description Steve Grubb 2012-08-30 15:41:35 UTC 
Description of problem:
pkexec, polkit-agent-helper-1, and polkitd are not compiled with gcc's PIE security flag. All setuid, network, and daemon programs should have PIE enabled so that each invocation has new ASLR. Additionally, daemons and setuid programs should have full RELRO and not partial.

FILE                                                TYPE        RELRO    PIE 
/usr/bin/pkexec                                     setuid      partial  no  
/usr/lib/polkit-1/polkit-agent-helper-1             setuid      partial  no  
/usr/lib/polkit-1/polkitd                           daemon      partial  no

Comment 1 Fedora Admin XMLRPC Client 2013-02-01 23:59:24 UTC 
This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
Comment 2 Steve Grubb 2013-03-07 16:46:56 UTC 
Checking to see if there is any progress on updating the compile flags? We'd like to close the bug if its fixed. Thanks.
Comment 3 Miloslav Trmač 2013-03-11 14:22:16 UTC 
Per changelog and rpm-chksec, polkit is currently built with PIE and full relro; I'll keep this report open to review the unusual way it's been enabled (not using %_hardened_build).
Comment 4 Matthias Clasen 2013-03-13 17:32:31 UTC 
See https://bugzilla.redhat.com/show_bug.cgi?id=892837 for that
Comment 5 Steve Grubb 2013-03-14 16:04:21 UTC 
Removing from CC tracker because its fixed as far as we are concerned.
Comment 6 Miloslav Trmač 2013-05-10 22:40:20 UTC 
Cause tracked down to bug 962005.
Comment 7 Miloslav Trmač 2013-09-18 20:02:15 UTC 
... and fixed for F18 in polkit-0.107-6.fc18 (not attached into the bodhi ticket, but will be published as an update eventually).
