Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated java-1.6.0-openjdk packages that fix two security issues are
now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
critical security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

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

It was discovered that the Beans component in OpenJDK did not perform
permission checks properly. An untrusted Java application or applet
could use this flaw to use classes from restricted packages, allowing
it to bypass Java sandbox restrictions. (CVE-2012-1682)

A hardening fix was applied to the AWT component in OpenJDK, removing
functionality from the restricted SunToolkit class that was used in
combination with other flaws to bypass Java sandbox restrictions.
(CVE-2012-0547)

Note: If the web browser plug-in provided by the icedtea-web package
was installed, the issues exposed via Java applets could have been
exploited without user interaction if a user visited a malicious
website.

This erratum also upgrades the OpenJDK package to IcedTea6 1.11.4.
Refer to the NEWS file, linked to in the References, for further
information.

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