Topic

Updated thermostat1-httpcomponents-client packages that fix one security
issue are now available for Red Hat Software Collections 1.

Red Hat Product Security has rated this update as having Important 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.

[Updated 25 August 2014]
This erratum previously incorrectly listed the CVE-2012-6153 issue as
addressed by this update. However, that issue did not affect the
thermostat1-httpcomponents-client packages.

Description

Thermostat is a monitoring and instrumentation tool for the OpenJDK HotSpot
Java Virtual Machine (JVM) with support for monitoring multiple
JVM instances.

The httpcomponents-client package provides an HTTP agent implementation
that is used by Thermostat to visualize collected data in an HTTP-aware
client application.

It was found that the fix for CVE-2012-6153 was incomplete: the code added
to check that the server hostname matches the domain name in a subject's
Common Name (CN) field in X.509 certificates was flawed.
A man-in-the-middle attacker could use this flaw to spoof an SSL server
using a specially crafted X.509 certificate. (CVE-2014-3577)

For additional information on this flaw, refer to the Knowledgebase
article in the References section.

All thermostat1-httpcomponents-client users are advised to upgrade to these
updated packages, which contain a backported patch to correct this issue.
