Package        : openjdk-6
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2011-3389 CVE-2011-3521 CVE-2011-3544 CVE-2011-3547 CVE-2011-3548 CVE-2011-3551 CVE-2011-3552 CVE-2011-3553 CVE-2011-3554 CVE-2011-3556 CVE-2011-3557 CVE-2011-3560

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.
