    firefox vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 13.10
    - Ubuntu 13.04
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Firefox could be made to crash or run programs as your login if it
    opened a malicious website.
    
    Software Description:
    - firefox: Mozilla Open Source web browser
    
    Details:
    
    Ben Turner, Bobby Holley, Jesse Ruderman, Christian Holler and Christoph
    Diehl discovered multiple memory safety issues in Firefox. If a user were
    tricked in to opening a specially crafted website, 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
    Firefox. (CVE-2013-5609, CVE-2013-5610)
    
    Myk Melez discovered that the doorhanger notification for web app
    installation could persist between page navigations. An attacker could
    potentially exploit this to conduct clickjacking attacks. (CVE-2013-5611)
    
    Masato Kinugawa discovered that pages with missing character set encoding
    information can inherit character encodings across navigations from
    another domain. An attacker could potentially exploit this to conduct
    cross-site scripting attacks. (CVE-2013-5612)
    
    Daniel Veditz discovered that a sandboxed iframe could use an object
    element to bypass its own restrictions. (CVE-2013-5614)
    
    Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in
    event listeners. 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 Firefox. (CVE-2013-5616)
    
    A use-after-free was discovered in the table editing interface. 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 Firefox. (CVE-2013-5618)
    
    Dan Gohman discovered that binary search algorithms in Spidermonkey
    used arithmetic prone to overflow in several places. However, this
    is issue not believed to be exploitable. (CVE-2013-5619)
    
    Tyson Smith and Jesse Schwartzentruber discovered a crash when inserting
    an ordered list in to a document using script. An attacker could
    potentially exploit this to execute arbitrary code with the privileges
    of the user invoking Firefox. (CVE-2013-6671)
    
    Vincent Lefevre discovered that web content could access clipboard data
    under certain circumstances, resulting in information disclosure.
    (CVE-2013-6672)
    
    Sijie Xia discovered that trust settings for built-in EV root certificates
    were ignored under certain circumstances, removing the ability for a user
    to manually untrust certificates from specific authorities.
    (CVE-2013-6673)
    
    Tyson Smith, Jesse Schwartzentruber and Atte Kettunen discovered a
    use-after-free in functions for synthetic mouse movement handling. 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 Firefox. (CVE-2013-5613)
    
    Eric Faust discovered that GetElementIC typed array stubs can be generated
    outside observed typesets. An attacker could possibly exploit this to
    cause undefined behaviour with a potential security impact.
    (CVE-2013-5615)
    
    Michal Zalewski discovered several issues with JPEG image handling. An
    attacker could potentially exploit these to obtain sensitive information.
    (CVE-2013-6629, CVE-2013-6630)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 13.10:
       firefox                         26.0+build2-0ubuntu0.13.10.2
    
    Ubuntu 13.04:
       firefox                         26.0+build2-0ubuntu0.13.04.2
    
    Ubuntu 12.10:
       firefox                         26.0+build2-0ubuntu0.12.10.2
    
    Ubuntu 12.04 LTS:
       firefox                         26.0+build2-0ubuntu0.12.04.2
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
