    firefox vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Several security issues were fixed in Firefox.
    
    Software Description:
    - firefox: Mozilla Open Source web browser
    
    Details:
    
    Benoit Jacob, Jesse Ruderman, Christian Holler, Bill McCloskey, Brian Smith,
    Gary Kwong, Christoph Diehl, Chris Jones, Brad Lassey, and Kyle Huey discovered
    memory safety issues affecting Firefox. If the user were tricked into opening a
    specially crafted page, an attacker could possibly exploit these to cause a
    denial of service via application crash, or potentially execute code with the
    privileges of the user invoking Firefox. (CVE-2012-1948, CVE-2012-1949)
    
    Mario Gomes discovered that the address bar may be incorrectly updated.
    Drag-and-drop events in the address bar may cause the address of the previous
    site to be displayed while a new page is loaded. An attacker could exploit this
    to conduct phishing attacks. (CVE-2012-1950)
    
    Abhishek Arya discovered four memory safety issues affecting Firefox. If the
    user were tricked into opening a specially crafted page, an attacker could
    possibly exploit these to cause a denial of service via application crash, or
    potentially execute code with the privileges of the user invoking Firefox.
    (CVE-2012-1951, CVE-2012-1952, CVE-2012-1953, CVE-2012-1954)
    
    Mariusz Mlynski discovered that the address bar may be incorrectly updated.
    Calls to history.forward and history.back could be used to navigate to a site
    while the address bar still displayed the previous site. A remote attacker
    could exploit this to conduct phishing attacks. (CVE-2012-1955)
    
    Mario Heiderich discovered that HTML  tags were not filtered out of the
    HTML  of RSS feeds. A remote attacker could exploit this to
    conduct cross-site scripting (XSS) attacks via javascript execution in the HTML
    feed view. (CVE-2012-1957)
    
    Arthur Gerkis discovered a use-after-free vulnerability. If the user were
    tricked into opening a specially crafted page, an attacker could possibly
    exploit this to cause a denial of service via application crash, or potentially
    execute code with the privileges of the user invoking Firefox. (CVE-2012-1958)
    
    Bobby Holley discovered that same-compartment security wrappers (SCSW) could be
    bypassed to allow XBL access. If the user were tricked into opening a specially
    crafted page, an attacker could possibly exploit this to execute code with the
    privileges of the user invoking Firefox. (CVE-2012-1959)
    
    Tony Payne discovered an out-of-bounds memory read in Mozilla's color
    management library (QCMS). If the user were tricked into opening a specially
    crafted color profile, an attacker could possibly exploit this to cause a
    denial of service via application crash. (CVE-2012-1960)
    
    Frédéric Buclin discovered that the X-Frame-Options header was ignored when its
    value was specified multiple times. An attacker could exploit this to conduct
    clickjacking attacks. (CVE-2012-1961)
    
    Bill Keese discovered a memory corruption vulnerability. If the user were
    tricked into opening a specially crafted page, an attacker could possibly
    exploit this to cause a denial of service via application crash, or potentially
    execute code with the privileges of the user invoking Firefox. (CVE-2012-1962)
    
    Karthikeyan Bhargavan discovered an information leakage vulnerability in the
    Content Security Policy (CSP) 1.0 implementation. If the user were tricked into
    opening a specially crafted page, an attacker could possibly exploit this to
    access a user's OAuth 2.0 access tokens and OpenID credentials. (CVE-2012-1963)
    
    Matt McCutchen discovered a clickjacking vulnerability in the certificate
    warning page. A remote attacker could trick a user into accepting a malicious
    certificate via a crafted certificate warning page. (CVE-2012-1964)
    
    Mario Gomes and Soroush Dalili discovered that javascript was not filtered out
    of feed URLs. If the user were tricked into opening a specially crafted URL, an
    attacker could possibly exploit this to conduct cross-site scripting (XSS)
    attacks. (CVE-2012-1965)
    
    A vulnerability was discovered in the context menu of data: URLs. If the user
    were tricked into opening a specially crafted URL, an attacker could possibly
    exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2012-1966)
    
    It was discovered that the execution of javascript: URLs was not properly
    handled in some cases. A remote attacker could exploit this to execute code
    with the privileges of the user invoking Firefox. (CVE-2012-1967)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      firefox                         14.0.1+build1-0ubuntu0.12.04.1
    
    Ubuntu 11.10:
      firefox                         14.0.1+build1-0ubuntu0.11.10.1
    
    Ubuntu 11.04:
      firefox                         14.0.1+build1-0ubuntu0.11.04.1
    
    Ubuntu 10.04 LTS:
      firefox                         14.0.1+build1-0ubuntu0.10.04.1
    
    When upgrading, users should be aware of the following:
    
    - In Ubuntu 11.04, unity-2d users may lose the ability to view drop-down menus,
    context menus, and perform drag-and-drop operations in Firefox. This is a known
    issue being tracked in https://launchpad.net/bugs/1020198 and may be fixed in a
    later update.
    
    After a standard system update you need to restart Firefox to make
    all the necessary changes.
