    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:
    
    Christian Holler and Patrick McManus 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-2014-8634)
    
    Muneaki Nishimura discovered that requests from navigator.sendBeacon()
    lack an origin header. 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-2014-8638)
    
    Xiaofeng Zheng discovered that a web proxy returning a 407 response
    could inject cookies in to the originally requested domain. If a user
    connected to a malicious web proxy, an attacker could potentially exploit
    this to conduct session-fixation attacks. (CVE-2014-8639)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      thunderbird                     1:31.4.0+build1-0ubuntu0.14.10.1
    
    Ubuntu 14.04 LTS:
      thunderbird                     1:31.4.0+build1-0ubuntu0.14.04.1
    
    Ubuntu 12.04 LTS:
      thunderbird                     1:31.4.0+build1-0ubuntu0.12.04.1
    
    After a standard system update you need to restart Thunderbird to make
    all the necessary changes.
