yum security update

CentOS Errata and Security Advisory CESA-2014:1004

The yum-updatesd package provides a daemon which checks for available
updates and can notify you when they are available via email, syslog,
or dbus.

It was discovered that yum-updatesd did not properly perform RPM package
signature checks. When yum-updatesd was configured to automatically install
updates, a remote attacker could use this flaw to install a malicious
update on the target system using an unsigned RPM or an RPM signed with an
untrusted key. (CVE-2014-0022)

All yum-updatesd users are advised to upgrade to this updated package,
which contains a backported patch to correct this issue. After installing
this update, the yum-updatesd service will be restarted automatically.
