    thunderbird vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.04
    - 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:
    
    Jesse Ruderman, Mats Palmgren, Byron Campen, and Steve Fink 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-2015-2708)
    
    Atte Kettunen discovered a buffer overflow during the rendering of SVG
    content with certain CSS properties 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 cause a denial of service
    via application crash, or execute arbitrary code with the privileges of
    the user invoking Thunderbird. (CVE-2015-2710)
    
    Scott Bell discovered a use-afer-free during the processing of text when
    vertical text is enabled. 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-2015-2713)
    
    Ucha Gobejishvili discovered a buffer overflow when parsing compressed XML
    content. If a user were tricked in to opening a specially crafted message
    with scripting enabled, 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-2015-2716)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.04:
      thunderbird                     1:31.7.0+build1-0ubuntu0.15.04.1
    
    Ubuntu 14.10:
      thunderbird                     1:31.7.0+build1-0ubuntu0.14.10.1
    
    Ubuntu 14.04 LTS:
      thunderbird                     1:31.7.0+build1-0ubuntu0.14.04.1
    
    Ubuntu 12.04 LTS:
      thunderbird                     1:31.7.0+build1-0ubuntu0.12.04.1
    
    After a standard system update you need to restart Thunderbird to make
    all the necessary changes.
