    3. Description:
    
    The IcedTea-Web project provides a Java web browser plug-in and an
    implementation of Java Web Start, which is based on the Netx project. It
    also contains a configuration tool for managing deployment settings for the
    plug-in and Web Start implementations.
    
    An uninitialized pointer use flaw was found in the IcedTea-Web plug-in.
    Visiting a malicious web page could possibly cause a web browser using the
    IcedTea-Web plug-in to crash, disclose a portion of its memory, or execute
    arbitrary code. (CVE-2012-3422)
    
    It was discovered that the IcedTea-Web plug-in incorrectly assumed all
    strings received from the browser were NUL terminated. When using the
    plug-in with a web browser that does not NUL terminate strings, visiting a
    web page containing a Java applet could possibly cause the browser to
    crash, disclose a portion of its memory, or execute arbitrary code.
    (CVE-2012-3423)
    
    Red Hat would like to thank Chamal De Silva for reporting the CVE-2012-3422
    issue.
    
    This erratum also upgrades IcedTea-Web to version 1.2.1. Refer to the NEWS
    file, linked to in the References, for further information.
    
    All IcedTea-Web users should upgrade to these updated packages, which
    resolve these issues. Web browsers using the IcedTea-Web browser plug-in
    must be restarted for this update to take effect.
    
    4. Solution:
