Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated cloud-init packages that fix one security issue, several bugs,
and add various enhancements are now available for Red Hat Common for
Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Low security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in
the References section.

The cloud-init packages provide a set of init scripts for cloud
instances. Cloud instances need special scripts to run during
initialization to retrieve and install ssh keys and to let the user
run various scripts.

A denial of service flaw was found in the way Python's SSL module
implementation performed matching of certain certificate names. A
remote attacker able to obtain a valid certificate that contained
multiple wildcard characters could use this flaw to issue a request to
validate such a certificate, resulting in excessive consumption of
CPU. (CVE-2013-2099)

This issue was discovered by Florian Weimer of Red Hat Product
Security.

The cloud-init packages have been upgraded to upstream version 0.7.5,
which provides a number of bug fixes and enhancements over the
previous version. (BZ#1111709, BZ#1119334)

All cloud-init users are advised to upgrade to these updated packages,
which correct these issues and add these enhancements.
