    thunderbird vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.10
    - 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:
    
    Olli Pettay and Boris Zbarsky discovered an issue during anchor
    navigations in some circumstances. If a user were tricked in to opening
    a specially crafted message with scripting enabled, an attacker could
    potentially exploit this to bypass same-origin policy restrictions.
    (CVE-2015-0801)
    
    Christoph Kerschbaumer discovered that CORS requests from
    navigator.sendBeacon() followed 30x redirections after preflight. If a
    user were tricked in to opening a specially crafted message with
    scripting enabled, an attacker could potentially exploit this to conduct
    cross-site request forgery (XSRF) attacks. (CVE-2015-0807)
    
    Aki Helin discovered a use-after-free when playing MP3 audio files using
    the Fluendo MP3 GStreamer plugin in certain circumstances. If a user were
    tricked in to opening a specially crafted message, 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-2015-0813)
    
    Christian Holler, Steve Fink, and Byron Campen discovered multiple memory
    safety issues in Thunderbird. If a user were tricked in to opening a
    specially crafted message with scripting enabled, 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-2015-0815)
    
    Mariusz Mlynski discovered that documents loaded via resource: URLs (such
    as PDF.js) could load privileged chrome pages. If a user were tricked in
    to opening a specially crafted message with scripting enabled, an attacker
    could potentially exploit this in combination with another flaw, in order
    to execute arbitrary script in a privileged context. (CVE-2015-0816)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      thunderbird                     1:31.6.0+build1-0ubuntu0.14.10.1
    
    Ubuntu 14.04 LTS:
      thunderbird                     1:31.6.0+build1-0ubuntu0.14.04.1
    
    Ubuntu 12.04 LTS:
      thunderbird                     1:31.6.0+build1-0ubuntu0.12.04.1
    
    After a standard system update you need to restart Thunderbird to make
    all the necessary changes.
