Synopsis
Low: cloud-init security, bug fix, and enhancement update
Type/Severity
Security Advisory: Low
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
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.
Description
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.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
