Debian: New OpenJDK packages fix security vulnerabilities

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

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. 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. 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.

A flaw was found in the AWT KeyboardFocusManager class that could allow untrusted Java applets to acquire keyboard focus and possibly steal sensitive information. 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. The Java serialization code leaked references to serialization exceptions, possibly leaking critical objects to untrusted code in Java applets and applications.

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. 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

Updated packages are available from security.debian.org.

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.
