icedtea-web regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10

Summary:

Due to a regression, IcedTea-Web might not be able to access some sites.

Software Description:
- icedtea-web: A web browser plugin to execute Java applets

Details:

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.

Original advisory details:

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
icedtea-7-plugin 1.2.3-0ubuntu0.12.04.2
icedtea-netx 1.2.3-0ubuntu0.12.04.2

Ubuntu 11.10:
icedtea-netx 1.2.3-0ubuntu0.11.10.2

After a standard system update you need to restart your browser to make
all the necessary changes.
