OVERVIEW

        Multiple vulnerabilities in Mozilla Firefox [1], Mozilla
        Thunderbird [2] and Mozilla Seamonkey [3] allow the execution of
        arbitrary code.


IMPACT

        The most severe of the vulnerabities allow the remote execution of
        arbitrary code without user interaction other than visiting a
        malicious web site.

        Other impacts include the inappropriate trusting of an invalid
        certificate and cross-site scripting. Thunderbird also contains
        vulnerabilities that may allow a maliciously constructed email to
        bypass security settings and execute Javascript even if Javascript
        had been disabled. Several denial of service (crash) vulnerabilities
        are also present in all three products.


MITIGATION

        Users of Firefox, Thunderbird and Seamonkey should upgrade to the
        latest versions of the software. For Firefox and Thunderbird, this
        is version 1.5.0.7, available at:

        http://www.mozilla.org/firefox

        and

        http://www.mozilla.org/thunderbird

        respectively. For Seamonkey this is version 1.0.5, available at:

        http://www.mozilla.org/projects/seamonkey/
