Synopsis
The remote Red Hat host is missing one or more security updates for icedtea-web.
Description
The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:0753 advisory.
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.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL icedtea-web package based on the guidance in RHSA-2013:0753.
