USN-1804-1 fixed vulnerabilities in IcedTea-Web. This update introduced a regression with the Java Network Launching Protocol (JNLP) when fetching content over SSL under certain configurations, such as when using the community-supported IcedTead 7 browser plugin.
This update fixes the problem.

We apologize for the inconvenience.

Jiri Vanek discovered that IcedTea-Web would use the same classloader for applets from different domains. A remote attacker could exploit this to expose sensitive information or potentially manipulate applets from other domains. (CVE-2013-1926)

It was discovered that IcedTea-Web did not properly verify JAR files and was susceptible to the GIFAR attack. If a user were tricked into opening a malicious website, a remote attacker could potentially exploit this to execute code under certain circumstances. (CVE-2013-1927).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.

This update to version 1.3.2 fixes several security updates and common fixes. (bnc#815596)
