    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 13.10
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Firefox could be made to crash or run programs as your login if it
    opened a malicious website.
    
    Software Description:
    - firefox: Mozilla Open Source web browser
    
    Details:
    
    Gary Kwong, Christoph Diehl, Christian Holler, Hannes Verschore, Jan de
    Mooij, Ryan VanderMeulen, Jeff Walden, Kyle Huey, Jesse Ruderman, Gregor
    Wagner, Benoit Jacob and Karl Tomlinson discovered multiple memory safety
    issues in Firefox. If a user were tricked in to opening a specially
    crafted website, an attacker could potentially exploit these to cause a
    denial of service via application crash, or execute arbitrary code with
    the privileges of the user invoking Firefox. (CVE-2014-1533,
    CVE-2014-1534)
    
    Abhishek Arya discovered multiple use-after-free and out-of-bounds read
    issues in Firefox. An attacker could potentially exploit these to cause
    a denial of service via application crash or execute arbitrary code with
    the priviliges of the user invoking Firefox. (CVE-2014-1536,
    CVE-2014-1537, CVE-2014-1538)
    
    Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in the
    event listener manager. An attacker could potentially exploit this to
    cause a denial of service via application crash or execute arbitrary code
    with the priviliges of the user invoking Firefox. (CVE-2014-1540)
    
    A use-after-free was discovered in the SMIL animation controller. An
    attacker could potentially exploit this to cause a denial of service via
    application crash or execute arbitrary code with the priviliges of the
    user invoking Firefox. (CVE-2014-1541)
    
    Holger Fuhrmannek discovered a buffer overflow in Web Audio. An attacker
    could potentially exploit this to cause a denial of service via
    application crash or execute arbitrary code with the priviliges of the
    user invoking Firefox. (CVE-2014-1542)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      firefox                         30.0+build1-0ubuntu0.14.04.3
    
    Ubuntu 13.10:
      firefox                         30.0+build1-0ubuntu0.13.10.3
    
    Ubuntu 12.04 LTS:
      firefox                         30.0+build1-0ubuntu0.12.04.3
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
