    firefox vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 13.10
    - Ubuntu 12.10
    - 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:
    
    Bobby Holley, Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij,
    Jesse Ruderman, Nathan Froyd, John Schoenick, Karl Tomlinson, Vladimir
    Vukicevic and Christian Holler 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-2014-1518, CVE-2014-1519)
    
    An out of bounds read was discovered in Web Audio. An attacker could
    potentially exploit this cause a denial of service via application crash
    or execute arbitrary code with the privileges of the user invoking
    Firefox. (CVE-2014-1522)
    
    Abhishek Arya discovered an out of bounds read when decoding JPG images.
    An attacker could potentially exploit this to cause a denial of service
    via application crash. (CVE-2014-1523)
    
    Abhishek Arya discovered a buffer overflow when a script uses a non-XBL
    object as an XBL object. An attacker could potentially exploit this to
    execute arbitrary code with the privileges of the user invoking Firefox.
    (CVE-2014-1524)
    
    Abhishek Arya discovered a use-after-free in the Text Track Manager when
    processing HTML video. An attacker could potentially exploit this to cause
    a denial of service via application crash or execute arbitrary code with
    the privileges of the user invoking Firefox. (CVE-2014-1525)
    
    Jukka Jylänki discovered an out-of-bounds write in Cairo when working
    with canvas in some circumstances. An attacker could potentially exploit
    this to cause a denial of service via application crash or execute
    arbitrary code with the privileges of the user invoking Firefox.
    (CVE-2014-1528)
    
    Mariusz Mlynski discovered that sites with notification permissions can
    run script in a privileged context in some circumstances. An attacker
    could exploit this to execute arbitrary code with the privileges of the
    user invoking Firefox. (CVE-2014-1529)
    
    It was discovered that browser history navigations could be used to load
    a site with the addressbar displaying the wrong address. An attacker could
    potentially exploit this to conduct cross-site scripting or phishing
    attacks. (CVE-2014-1530)
    
    A use-after-free was discovered when resizing images in some
    circumstances. An attacker could potentially exploit this to cause a
    denial of service via application crash or execute arbitrary code with the
    privileges of the user invoking Firefox. (CVE-2014-1531)
    
    Christian Heimes discovered that NSS did not handle IDNA domain prefixes
    correctly for wildcard certificates. An attacker could potentially exploit
    this by using a specially crafted certificate to conduct a man-in-the-middle
    attack. (CVE-2014-1492)
    
    Tyson Smith and Jesse Schwartzentruber discovered a use-after-free during
    host resolution in some circumstances. An attacker could potentially
    exploit this to cause a denial of service via application crash or execute
    arbitrary code with the privileges of the user invoking Firefox.
    (CVE-2014-1532)
    
    Boris Zbarsky discovered that the debugger bypassed XrayWrappers for some
    objects. If a user were tricked in to opening a specially crafted website
    whilst using the debugger, an attacker could potentially exploit this to
    execute arbitrary code with the privileges of the user invoking Firefox.
    (CVE-2014-1526)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      firefox                         29.0+build1-0ubuntu0.14.04.2
    
    Ubuntu 13.10:
      firefox                         29.0+build1-0ubuntu0.13.10.3
    
    Ubuntu 12.10:
      firefox                         29.0+build1-0ubuntu0.12.10.3
    
    Ubuntu 12.04 LTS:
      firefox                         29.0+build1-0ubuntu0.12.04.2
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
