Scientific Linux Security Update : icedtea-web on SL6.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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.

This erratum also upgrades IcedTea-Web to version 1.2.3.

Web browsers using the IcedTea-Web browser plug-in must be restarted
for this update to take effect.
