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 websites that allow uploads of specific file types, known as a GIFAR attack.
(CVE-2013-1927)
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.
