Red Hat Security Advisory: java-1.6.0-openjdk security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1221 Final 1 1 2012-09-03T12:25:00Z Current version 2012-09-03T12:25:00Z 2012-09-03T12:25:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-09-03T12:40:02Z 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.
