    thunderbird vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.10
    - Ubuntu 15.04
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Several security issues were fixed in Thunderbird.
    
    Software Description:
    - thunderbird: Mozilla Open Source mail and newsgroup client
    
    Details:
    
    Christian Holler, David Major, Jesse Ruderman, Tyson Smith, Boris Zbarsky,
    Randell Jesup, Olli Pettay, Karl Tomlinson, Jeff Walden, and Gary Kwong
    discovered multiple memory safety issues in Thunderbird. If a user were
    tricked in to opening a specially crafted message, 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
    Thunderbird. (CVE-2015-4513)
    
    Tyson Smith and David Keeler discovered a use-after-poison and buffer
    overflow in NSS. 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 Thunderbird. (CVE-2015-7181,
    CVE-2015-7182)
    
    Ryan Sleevi discovered an integer overflow in NSPR. 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
    Thunderbird. (CVE-2015-7183)
    
    Michał Bentkowski discovered that adding white-space to hostnames that are
    IP addresses can bypass same-origin protections. If a user were tricked in
    to opening a specially crafted website in a browser-like context, an
    attacker could potentially exploit this to conduct cross-site scripting
    (XSS) attacks. (CVE-2015-7188)
    
    Looben Yang discovered a buffer overflow during script interactions with
    the canvas element in some circumstances. If a user were tricked in to
    opening a specially crafted website in a browser-like context, 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 Thunderbird. (CVE-2015-7189)
    
    Shinto K Anto discovered that CORS preflight is bypassed when receiving
    non-standard Content-Type headers in some circumstances. If a user were
    tricked in to opening a specially crafted website in a browser-like
    context, an attacker could potentially exploit this to bypass
    same-origin restrictions. (CVE-2015-7193)
    
    Gustavo Grieco discovered a buffer overflow in libjar in some
    circumstances. If a user were tricked in to opening a specially crafted
    website in a browser-like context, 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 Thunderbird.
    (CVE-2015-7194)
    
    Ehsan Akhgari discovered a mechanism for a web worker to bypass secure
    requirements for web sockets. If a user were tricked in to opening a
    specially crafted website in a browser-like context, an attacker could
    exploit this to bypass the mixed content web socket policy.
    (CVE-2015-7197)
    
    Ronald Crane discovered several vulnerabilities through code-inspection. If
    a user were tricked in to opening a specially crafted website in a
    browser-like context, 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 Thunderbird. (CVE-2015-7198,
    CVE-2015-7199, CVE-2015-7200)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.10:
      thunderbird                     1:38.4.0+build3-0ubuntu0.15.10.1
    
    Ubuntu 15.04:
      thunderbird                     1:38.4.0+build3-0ubuntu0.15.04.1
    
    Ubuntu 14.04 LTS:
      thunderbird                     1:38.4.0+build3-0ubuntu0.14.04.1
    
    Ubuntu 12.04 LTS:
      thunderbird                     1:38.4.0+build3-0ubuntu0.12.04.1
    
    After a standard system update you need to restart Thunderbird to make
    all the necessary changes.
