    openjdk-6 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Several security issues were fixed in OpenJDK 6.
    
    Software Description:
    - openjdk-6: Open Source Java implementation
    
    Details:
    
    It was discovered that OpenJDK did not restrict the set of algorithms used
    for Jar integrity verification. An attacker could use this to modify
    without detection the content of a JAR file, affecting system integrity.
    (CVE-2016-5542)
    
    It was discovered that the JMX component of OpenJDK did not sufficiently
    perform classloader consistency checks. An attacker could use this to
    bypass Java sandbox restrictions. (CVE-2016-5554)
    
    It was discovered that the Hotspot component of OpenJDK did not properly
    check received Java Debug Wire Protocol (JDWP) packets. An attacker could
    use this to send debugging commands to a Java application with debugging
    enabled. (CVE-2016-5573)
    
    It was discovered that the Hotspot component of OpenJDK did not properly
    check arguments of the System.arraycopy() function in certain cases. An
    attacker could use this to bypass Java sandbox restrictions.
    (CVE-2016-5582)
    
    It was discovered that OpenJDK did not properly handle HTTP proxy
    authentication. An attacker could use this to expose HTTPS server
    authentication credentials. (CVE-2016-5597)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      icedtea-6-jre-cacao             6b40-1.13.12-0ubuntu0.12.04.2
      icedtea-6-jre-jamvm             6b40-1.13.12-0ubuntu0.12.04.2
      openjdk-6-jdk                   6b40-1.13.12-0ubuntu0.12.04.2
      openjdk-6-jre                   6b40-1.13.12-0ubuntu0.12.04.2
      openjdk-6-jre-headless          6b40-1.13.12-0ubuntu0.12.04.2
      openjdk-6-jre-lib               6b40-1.13.12-0ubuntu0.12.04.2
    
    After a standard system update you need to restart any Java
    applications or applets to make all the necessary changes.
