    Several vulnerabilities have been discovered in OpenJDK, an
    implementation of the Java platform:
    
    CVE-2011-3389
    	The TLS implementation does not guard properly against certain
    	chosen-plaintext attacks when block ciphers are used in CBC
    	mode.
    
    CVE-2011-3521
    	The CORBA implementation contains a deserialization
    	vulnerability in the IIOP implementation, allowing untrusted
    	Java code (such as applets) to elevate its privileges.
    
    CVE-2011-3544
    	The Java scripting engine lacks necessary security manager
    	checks, allowing untrusted Java code (such as applets) to
    	elevate its privileges.
    
    CVE-2011-3547
    	The skip() method in java.io.InputStream uses a shared buffer,
    	allowing untrusted Java code (such as applets) to access data
    	that is skipped by other code.
    
    CVE-2011-3548
    	The java.awt.AWTKeyStroke class contains a flaw which allows
    	untrusted Java code (such as applets) to elevate its
    	privileges.
    
    CVE-2011-3551
    	The Java2D C code contains an integer overflow which results
    	in a heap-based buffer overflow, potentially allowing
    	untrusted Java code (such as applets) to elevate its
    	privileges.
    
    CVE-2011-3552
    	Malicous Java code can use up an excessive amount of UDP
    	ports, leading to a denial of service.
    
    CVE-2011-3553
    	JAX-WS enables stack traces for certain server responses by
    	default, potentially leaking sensitive information.
    
    CVE-2011-3554
    	JAR files in pack200 format are not properly checked for
    	errors, potentially leading to arbitrary code execution when
    	unpacking crafted pack200 files.
    
    CVE-2011-3556
    	The RMI Registry server lacks access restrictions on certain
    	methods, allowing a remote client to execute arbitary code.
    
    CVE-2011-3557
    	The RMI Registry server fails to properly restrict privileges
    	of untrusted Java code, allowing RMI clients to elevate their
    	privileges on the RMI Registry server.
    
    CVE-2011-3560
    	The com.sun.net.ssl.HttpsURLConnection class does not perform
    	proper security manager checks in the setSSLSocketFactory()
    	method, allowing untrusted Java code to bypass security policy
    	restrictions.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 6b18-1.8.10-0+squeeze1.
    
    For the testing distribution (wheezy) and the unstable distribution
    (sid), this problem has been fixed in version 6b23~pre11-1.
    
    We recommend that you upgrade your openjdk-6 packages.
