1. Summary:

Updated icedtea-web packages that fix two security issues are now available
for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,

3. Description:

The IcedTea-Web project provides a Java web browser plug-in and an
implementation of Java Web Start, which is based on the Netx project. It
also contains a configuration tool for managing deployment settings for the
plug-in and Web Start implementations.

It was discovered that the IcedTea-Web plug-in incorrectly used the same
class loader instance for applets with the same value of the codebase
attribute, even when they originated from different domains. A malicious
applet could use this flaw to gain information about and possibly
manipulate applets from different domains currently running in the browser.
(CVE-2013-1926)

The IcedTea-Web plug-in did not properly check the format of the downloaded
Java Archive (JAR) files. This could cause the plug-in to execute code
hidden in a file in a different format, possibly allowing attackers to
execute code in the context of web sites that allow uploads of specific
file types, known as a GIFAR attack. (CVE-2013-1927)

The CVE-2013-1926 issue was discovered by Jiri Vanek of the Red Hat OpenJDK
Team, and CVE-2013-1927 was discovered by the Red Hat Security Response
Team.

This erratum also upgrades IcedTea-Web to version 1.2.3. Refer to the NEWS
file, linked to in the References, for further information.

All IcedTea-Web users should upgrade to these updated packages, which
resolve these issues. Web browsers using the IcedTea-Web browser plug-in
must be restarted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

884705 - CVE-2013-1927 icedtea-web: GIFAR issue
