==========================================================================
Ubuntu Security Notice USN-1154-1
June 17, 2011

openjdk-6, openjdk-6b18 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

Multiple OpenJDK 6 vulnerabilities have been fixed.

Software Description:
- openjdk-6: Open Source Java implementation
- openjdk-6b18: Open Source Java implementation

Details:

It was discovered that a heap overflow in the AWT FileDialog.show()
method could allow an attacker to cause a denial of service through an
application crash or possibly execute arbitrary code. (CVE-2011-0815)

It was dicovered that integer overflows in the JPEGImageReader
readImage() function and the SunLayoutEngine nativeLayout() function
could allow an attacker to cause a denial of service through an
application crash or possibly execute arbitrary code. (CVE-2011-0822,
CVE-2011-0862)

It was discovered that memory corruption could occur when interpreting
bytecode in the HotSpot VM. This could allow an attacker to cause a
denial of service through an application crash or possibly execute
arbitrary code. (CVE-2011-0864)

It was discovered that the deserialization code allowed the creation
of mutable SignedObjects. This could allow an attacker to possibly
execute code with elevated privileges. (CVE-2011-0865)

It was discovered that the toString method in the NetworkInterface
class would reveal multiple addresses if they were bound to the
interface. This could give an attacker more information about the
networking environment. (CVE-2011-0867)

It was discovered that the Java 2D code to transform an image with a
scale close to 0 could trigger an integer overflow. This could allow
an attacker to cause a denial of service through an application crash
or possibly execute arbitrary code. (CVE-2011-0868)

It was discovered that the SOAP with Attachments API for Java (SAAJ)
implementation allowed the modification of proxy settings via
unprivileged SOAP messages. (CVE-2011-0869, CVE-2011-0870)

It was the discovered that the Swing ImageIcon class created
MediaTracker objects that potentially leaked privileged
ApplicationContexts. This could possibly allow an attacker access to
restricted resources or services. (CVE-2011-0871)

It was discovered that non-blocking sockets marked as not urgent could
still get selected for read operations. This could allow an attacker
to cause a denial of service. (CVE-2011-0872)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
  openjdk-6-jre                   6b22-1.10.2-0ubuntu1~11.04.1
  openjdk-6-jre-headless          6b22-1.10.2-0ubuntu1~11.04.1
  openjdk-6-jre-lib               6b22-1.10.2-0ubuntu1~11.04.1

Ubuntu 10.10:
  icedtea6-plugin                 6b20-1.9.8-0ubuntu1~10.10.1
  openjdk-6-jre                   6b20-1.9.8-0ubuntu1~10.10.1
  openjdk-6-jre-headless          6b20-1.9.8-0ubuntu1~10.10.1
  openjdk-6-jre-lib               6b20-1.9.8-0ubuntu1~10.10.1

Ubuntu 10.04 LTS:
  icedtea6-plugin                 6b20-1.9.8-0ubuntu1~10.04.1
  openjdk-6-jre                   6b20-1.9.8-0ubuntu1~10.04.1
  openjdk-6-jre-headless          6b20-1.9.8-0ubuntu1~10.04.1
  openjdk-6-jre-lib               6b20-1.9.8-0ubuntu1~10.04.1

After a standard system update you need to restart any Java services,
applications or applets to make all the necessary changes.
