Red Hat: 2012:1221-01: java-1.6.0-openjdk: Critical Advisory
Summary
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.
Summary
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
