    Details:
    
    Francis Gabriel discovered a buffer overflow during ASN.1 decoding in NSS.
    If a user were tricked in to opening a specially crafted website, 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-2016-1950)
    
    Bob Clary, Christoph Diehl, Christian Holler, Andrew McCreight, Daniel
    Holbert, Jesse Ruderman, Randell Jesup, Carsten Book, Gian-Carlo Pascutto,
    Tyson Smith, Andrea Marchesini, and Jukka Jylänki 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-2016-1952,
    CVE-2016-1953)
    
    Nicolas Golubovic discovered that CSP violation reports can be used to

    an attacker could potentially exploit this to gain additional privileges.
    (CVE-2016-1954)
    
    Muneaki Nishimura discovered that CSP violation reports contained full
    paths for cross-origin iframe navigations. An attacker could potentially

    Ucha Gobejishvili discovered that performing certain WebGL operations
    resulted in memory resource exhaustion with some Intel GPUs, requiring
    a reboot. If a user were tricked in to opening a specially crafted
    website, an attacker could potentially exploit this to cause a denial
    of service. (CVE-2016-1956)
    
    Jose Martinez and Romina Santillan discovered a memory leak in
    libstagefright during MPEG4 video file processing in some circumstances.
    If a user were tricked in to opening a specially crafted website, an
    attacker could potentially exploit this to cause a denial of service via
    memory exhaustion. (CVE-2016-1957)
    
    Abdulrahman Alqabandi discovered that the addressbar could be blank or
    filled with page defined content in some circumstances. If a user were
    tricked in to opening a specially crafted website, an attacker could
    potentially exploit this to conduct URL spoofing attacks. (CVE-2016-1958)
    
    Looben Yang discovered an out-of-bounds read in Service Worker Manager. If
    a user were tricked in to opening a specially crafted website, 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-2016-1959)
    
    A use-after-free was discovered in the HTML5 string parser. If a user were
    tricked in to opening a specially crafted website, 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-2016-1960)
    
    A use-after-free was discovered in the SetBody function of HTMLDocument.
    If a user were tricked in to opening a specially crafted website, 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-2016-1961)
    
    Dominique Hazaël-Massieux discovered a use-after-free when using multiple
    WebRTC data channels. If a user were tricked in to opening a specially

    the privileges of the user invoking Firefox. (CVE-2016-1962)
    
    It was discovered that Firefox crashes when local files are modified
    whilst being read by the FileReader API. If a user were tricked in to
    opening a specially crafted website, an attacker could potentially exploit
    this to execute arbitrary code with the privileges of the user invoking
    Firefox. (CVE-2016-1963)
    
    Nicolas Grégoire discovered a use-after-free during XML transformations.

    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.10:
      firefox                         45.0+build2-0ubuntu0.15.10.1
    
    Ubuntu 14.04 LTS:
      firefox                         45.0+build2-0ubuntu0.14.04.1
    
    Ubuntu 12.04 LTS:
      firefox                         45.0+build2-0ubuntu0.12.04.1
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
