red hat
February 16, 2016
Updated polkit packages that fix one security issue are now available for Red Hat Enterprise Linux 7
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
For details on how to apply this update, refer to:

Summary
PolicyKit is a toolkit for defining and handling authorizations.
A denial of service flaw was found in how polkit handled authorization
requests. A local, unprivileged user could send malicious requests to
polkit, which could then cause the polkit daemon to corrupt its memory and
crash. (CVE-2015-3256)
All polkit users should upgrade to these updated packages, which contain a
backported patch to correct this issue. The system must be rebooted for
this update to take effect.
