package(s) announced via the referenced advisory.
Vulnerability Insight:
The bash packages provide Bash
(Bourne-again shell), which is the default shell for Red Hat Enterprise Linux.
Security Fix(es):

arbitrary commands on the DHCP client machines running bash under specific
circumstances. (CVE-2016-0634)

elevate their privileges under certain circumstances. (CVE-2016-7543)
* A denial of service flaw was found in the way bash handled popd commands.

local denial of service limited to a specific bash session. (CVE-2016-9401)
