    icedtea-web vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 10.04 LTS
    Two security issues were fixed in IcedTea-Web.
    Software Description:
    - icedtea-web: A web browser plugin to execute Java applets
    Jiri Vanek discovered that IcedTea-Web would use the same classloader for
    applets from different domains. A remote attacker could exploit this to
    expose sensitive information or potentially manipulate applets from other
    domains. (CVE-2013-1926)
    It was discovered that IcedTea-Web did not properly verify JAR files and
    was susceptible to the GIFAR attack. If a user were tricked into opening a
    malicious website, a remote attacker could potentially exploit this to
    execute code under certain circumstances. (CVE-2013-1927)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 12.10:
      icedtea-netx                    1.3.2-1ubuntu0.12.10.1
    Ubuntu 12.04 LTS:
      icedtea-netx                    1.2.3-0ubuntu0.12.04.1
    Ubuntu 11.10:
      icedtea-netx                    1.2.3-0ubuntu0.11.10.1
    Ubuntu 10.04 LTS:
      icedtea-netx                    1.2.3-0ubuntu0.10.04.1
    After a standard system update you need to restart your browser to make
    all the necessary changes.
