    thunderbird vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.04
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Multiple vulnerabilities were fixed in Thunderbird.
    
    Software Description:
    - thunderbird: Mozilla Open Source mail and newsgroup client
    
    Details:
    
    Multiple memory vulnerabilities were discovered in the browser rendering
    engine. An attacker could use these to possibly execute arbitrary code with
    the privileges of the user invoking Thunderbird. (CVE-2011-2364,
    CVE-2011-2365, CVE-2011-2374, CVE-2011-2376)
    
    Martin Barbella discovered that under certain conditions, viewing a XUL
    document while JavaScript was disabled caused deleted memory to be
    accessed. An attacker could potentially use this to crash Thunderbird or
    execute arbitrary code with the privileges of the user invoking
    Thunderbird. (CVE-2011-2373)
     
    Jordi Chancel discovered a vulnerability on multipart/x-mixed-replace
    images due to memory corruption. An attacker could potentially use this to
    crash Thunderbird or execute arbitrary code with the privileges of the user
    invoking Thunderbird. (CVE-2011-2377)
     
    Chris Rohlf and Yan Ivnitskiy discovered an integer overflow vulnerability
    in JavaScript Arrays. An attacker could potentially use this to execute
    arbitrary code with the privileges of the user invoking Thunderbird.
    (CVE-2011-2371)
    
    Multiple use-after-free vulnerabilities were discovered. An attacker could
    potentially use these to execute arbitrary code with the privileges of the
    user invoking Thunderbird. (CVE-2011-0083, CVE-2011-0085, CVE-2011-2363)
    
    David Chan discovered that cookies did not honor same-origin conventions.
    This could potentially lead to cookie data being leaked to a third party.
    (CVE-2011-2362)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.04:
      thunderbird                     3.1.11+build2+nobinonly-0ubuntu0.11.04.1
    
    Ubuntu 10.10:
      thunderbird                     3.1.11+build2+nobinonly-0ubuntu0.10.10.1
    
    Ubuntu 10.04 LTS:
      thunderbird                     3.1.11+build2+nobinonly-0ubuntu0.10.04.1
    
    After a standard system update you need to restart Thunderbird to make
    all the necessary changes.
