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 websites that allow uploads of specific file types, known as a GIFAR attack.
