"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."
