Name        : polkit
Product     : Fedora 19
Version     : 0.112
Release     : 1.fc19
URL         : http://www.freedesktop.org/wiki/Software/polkit
Summary     : An authorization framework
Description :
polkit is a toolkit for defining and handling authorizations.  It is
used for allowing unprivileged processes to speak to privileged
processes.

--------------------------------------------------------------------------------
Update Information:

This release fixes CVE-2013-4288: Race condition with process subjects that do not have securely determined uid.

pkcheck(1) now supports a new format for the --process argument; all applications need to use the new format to avoid a race condition (or use --system-bus-name to identify the process instead).

Similarly, applications using the API should always use polkit_unix_process_new_for_owner().  polkit_unix_process_new() and polkit_unix_process_new_full() are unsafe and have been deprecated.

Thanks to Sebastian Krahmer of the SUSE Security Team for reporting this issue.
