Description

CentOS Errata and Security Advisory CESA-2012:1221

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.
