icedtea-web regression
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04

Summary:

USN 1505-1 introduced a regression in the IcedTea-Web Java web browser
plugin that prevented it from working with the Chromium web browser.

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

Details:

USN-1505-1 fixed vulnerabilities in OpenJDK 6. As part of the update,
IcedTea-Web packages were upgraded to a new version. That upgrade
introduced a regression which prevented the IcedTea-Web plugin from
working with the Chromium web browser in Ubuntu 11.04 and Ubuntu 11.10.
This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that multiple flaws existed in the CORBA (Common
Object Request Broker Architecture) implementation in OpenJDK. An
attacker could create a Java application or applet that used these
flaws to bypass Java sandbox restrictions or modify immutable object
data. (CVE-2012-1711, CVE-2012-1719)

It was discovered that multiple flaws existed in the OpenJDK font
manager's layout lookup implementation. A attacker could specially
craft a font file that could cause a denial of service through
crashing the JVM (Java Virtual Machine) or possibly execute arbitrary
code. (CVE-2012-1713)

It was discovered that the SynthLookAndFeel class from Swing in
OpenJDK did not properly prevent access to certain UI elements
from outside the current application context. An attacker could
create a Java application or applet that used this flaw to cause a
denial of service through crashing the JVM or bypass Java sandbox
restrictions. (CVE-2012-1716)

It was discovered that OpenJDK runtime library classes could create
temporary files with insecure permissions. A local attacker could
use this to gain access to sensitive information. (CVE-2012-1717)

It was discovered that OpenJDK did not handle CRLs (Certificate
Revocation Lists) properly. A remote attacker could use this to gain
access to sensitive information. (CVE-2012-1718)

It was discovered that the OpenJDK HotSpot Virtual Machine did not
properly verify the bytecode of the class to be executed. A remote
attacker could create a Java application or applet that used this
to cause a denial of service through crashing the JVM or bypass Java
sandbox restrictions. (CVE-2012-1723, CVE-2012-1725)

It was discovered that the OpenJDK XML (Extensible Markup Language)
parser did not properly handle some XML documents. An attacker could
create an XML document that caused a denial of service in a Java
application or applet parsing the document. (CVE-2012-1724)

As part of this update, the IcedTea web browser applet plugin was
updated for Ubuntu 10.04 LTS, Ubuntu 11.04, and Ubuntu 11.10.

Update instructions:

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

Ubuntu 11.10:
icedtea-6-plugin 1.2-2ubuntu0.11.10.3

Ubuntu 11.04:
icedtea-6-plugin 1.2-2ubuntu0.11.04.3

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