Several vulnerabilities have been discovered in OpenJDK, an
implementation of the Oracle Java platform.

CVE-2011-3377
        The Iced Tea browser plugin included in the openjdk-6 package
        does not properly enforce the Same Origin Policy on web content
        served under a domain name which has a common suffix with the
        required domain name.

CVE-2011-3563
        The Java Sound component did not properly check for array
        boundaries.  A malicious input or an untrusted Java application
        or applet could use this flaw to cause Java Virtual Machine to
        crash or disclose portion of its memory.

CVE-2011-5035
        The OpenJDK embedded web server did not guard against an
        excessive number of a request parameters, leading to a denial
        of service vulnerability involving hash collisions.

CVE-2012-0497
        It was discovered that Java2D did not properly check graphics
        rendering objects before passing them to the native renderer.
        This could lead to JVM crash or Java sandbox bypass.

CVE-2012-0501
        The ZIP central directory parser used by java.util.zip.ZipFile
        entered an infinite recursion in native code when processing a
        crafted ZIP file, leading to a denial of service.

CVE-2012-0502
        A flaw was found in the AWT KeyboardFocusManager class that
        could allow untrusted Java applets to acquire keyboard focus
        and possibly steal sensitive information.

CVE-2012-0503
        The java.util.TimeZone.setDefault() method lacked a security
        manager invocation, allowing an untrusted Java application or
        applet to set a new default time zone.

CVE-2012-0505
        The Java serialization code leaked references to serialization
        exceptions, possibly leaking critical objects to untrusted
        code in Java applets and applications.

CVE-2012-0506
        It was discovered that CORBA implementation in Java did not
        properly protect repository identifiers (that can be obtained
        using _ids() method) on certain Corba objects.  This could
        have been used to perform modification of the data that should
        have been immutable.

CVE-2012-0507
        The AtomicReferenceArray class implementation did not properly
        check if the array is of an expected Object[] type.  A
        malicious Java application or applet could use this flaw to
        cause Java Virtual Machine to crash or bypass Java sandbox
        restrictions

For the stable distribution (squeeze), these problems have been fixed in
version 6b18-1.8.13-0+squeeze1.

For the testing distribution (wheezy) and the unstable distribution
(sid), these problems have been fixed in version 6b24-1.11.1-1.

We recommend that you upgrade your openjdk-6 packages.
