    Package : iceweasel
    Vulnerability : several
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2012-1948 CVE-2012-1950 CVE-2012-1954 CVE-2012-1966
    CVE-2012-1967

    Several vulnerabilities have been discovered in Iceweasel, a web
    browser based on Firefox. The included XULRunner library provides
    rendering services for several other applications included in Debian.

    CVE-2012-1948

    Benoit Jacob, Jesse Ruderman, Christian Holler, and Bill McCloskey
    identified several memory safety problems that may lead to the
    execution of arbitrary code.

    CVE-2012-1950

    Mario Gomes and Code Audit Labs discovered that it is possible
    to force iceweasel to display the URL of the previous entered site
    through drag and drop actions to the address bar. This can be
    abused to perform phishing attacks.

    CVE-2012-1954

    Abhishek Arya discovered a use-after-free problem in nsDocument::AdoptNode
    that may lead to the execution of arbitrary code.

    CVE-2012-1966

    moz_bug_r_a4 discovered that it is possible to perform cross-site
    scripting attacks through the context menu when using data: URLs.

    CVE-2012-1967

    moz_bug_r_a4 discovered that in certain cases, javascript: URLs can
    be executed so that scripts can escape the JavaScript sandbox and run
    with elevated privileges.

    Note: We'd like to advise users of Iceweasel's 3.5 branch in Debian
    stable to consider to upgrade to the Iceweasel 10.0 ESR (Extended
    Support Release) which is now available in Debian Backports.
    Although Debian will continue to support Iceweasel 3.5 in stable with
    security updates, this can only be done on a best effort base as
    upstream provides no such support anymore. On top of that, the 10.0
    branch adds proactive security features to the browser.


    For the stable distribution (squeeze), this problem has been fixed in
    version 3.5.16-17.

    For the unstable distribution (sid), this problem has been fixed in
    version 10.0.6esr-1.


    We recommend that you upgrade your iceweasel packages.
