RHEL 5 : java-1.6.0-openjdk (RHSA-2012:0322)

critical Nessus Plugin ID 58084


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


Updated java-1.6.0-openjdk packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important 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 Java2D did not properly check graphics rendering objects before passing them to the native renderer.
Malicious input, or an untrusted Java application or applet could use this flaw to crash the Java Virtual Machine (JVM), or bypass Java sandbox restrictions. (CVE-2012-0497)

It was discovered that the exception thrown on deserialization failure did not always contain a proper identification of the cause of the failure. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions. (CVE-2012-0505)

The AtomicReferenceArray class implementation did not properly check if the array was of the expected Object[] type. A malicious Java application or applet could use this flaw to bypass Java sandbox restrictions. (CVE-2011-3571)

It was discovered that the use of TimeZone.setDefault() was not restricted by the SecurityManager, allowing an untrusted Java application or applet to set a new default time zone, and hence bypass Java sandbox restrictions. (CVE-2012-0503)

The HttpServer class did not limit the number of headers read from HTTP requests. A remote attacker could use this flaw to make an application using HttpServer use an excessive amount of CPU time via a specially crafted request. This update introduces a header count limit controlled using the sun.net.httpserver.maxReqHeaders property. The default value is 200. (CVE-2011-5035)

The Java Sound component did not properly check buffer boundaries.
Malicious input, or an untrusted Java application or applet could use this flaw to cause the Java Virtual Machine (JVM) to crash or disclose a portion of its memory. (CVE-2011-3563)

A flaw was found in the AWT KeyboardFocusManager that could allow an untrusted Java application or applet to acquire keyboard focus and possibly steal sensitive information. (CVE-2012-0502)

It was discovered that the CORBA (Common Object Request Broker Architecture) implementation in Java did not properly protect repository identifiers on certain CORBA objects. This could have been used to modify immutable object data. (CVE-2012-0506)

An off-by-one flaw, causing a stack overflow, was found in the unpacker for ZIP files. A specially crafted ZIP archive could cause the Java Virtual Machine (JVM) to crash when opened. (CVE-2012-0501)

This erratum also upgrades the OpenJDK package to IcedTea6 1.10.6.
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.
