These packages provide the OpenJDK 6 Java Runtime Environment and the
OpenJDK 6 Software Development Kit.

Integer overflow flaws were found in the way Java2D parsed JPEG images 
and user-supplied fonts. An attacker could use these flaws to execute 
arbitrary code with the privileges of the user running an untrusted 
applet or application. (CVE-2011-0862)

It was found that the MediaTracker implementation created Component
instances with unnecessary access privileges. A remote attacker could 
use this flaw to elevate their privileges by utilizing an untrusted 
applet or application that uses Swing. (CVE-2011-0871)

A flaw was found in the HotSpot component in OpenJDK. Certain bytecode
instructions confused the memory management within the Java Virtual 
Machine (JVM), resulting in an applet or application crashing. 
(CVE-2011-0864)

An information leak flaw was found in the NetworkInterface class. An
untrusted applet or application could use this flaw to access 
information about available network interfaces that should only be 
available to privileged code. (CVE-2011-0867)

An incorrect float-to-long conversion, leading to an overflow, was found
in the way certain objects (such as images and text) were transformed in
Java2D. A remote attacker could use this flaw to crash an untrusted 
applet or application that uses Java2D. (CVE-2011-0868)

It was found that untrusted applets and applications could misuse a SOAP
connection to incorrectly set global HTTP proxy settings instead of
setting them in a local scope. This flaw could be used to intercept HTTP
requests. (CVE-2011-0869)

A flaw was found in the way signed objects were deserialized. If trusted
and untrusted code were running in the same Java Virtual Machine (JVM), 
and both were deserializing the same signed object, the untrusted code 
could modify said object by using this flaw to bypass the validation 
checks on signed objects. (CVE-2011-0865)

Note: All of the above flaws can only be remotely triggered in OpenJDK 
by calling the "appletviewer" application.

All users of java-1.6.0-openjdk are advised to upgrade to these updated
packages, which provide OpenJDK 6 b20 / IcedTea 1.9.8 and resolve these
issues. All running instances of OpenJDK Java must be restarted for the
update to take effect.
