Mandriva Linux Security Advisory : polkit (MDVSA-2013:243)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Updated polkit packages fix security vulnerability :

A race condition was found in the way the PolicyKit pkcheck utility
checked process authorization when the process was specified by its
process ID via the --process option. A local user could use this flaw
to bypass intended PolicyKit authorizations and escalate their
privileges (CVE-2013-4288).

Note: Applications that invoke pkcheck with the --process option need
to be modified to use the pid,pid-start-time,uid argument for that
option, to allow pkcheck to check process authorization correctly.

Because of the change in the PolicyKit API, hplip (CVE-2013-4325),
rtkit (CVE-2013-4326), and systemd (CVE-2013-4327) packages have been
updated to use a different API that is not affected by this PolicyKit
vulnerability.
