OVERVIEW:

        Information has been released regarding multiple vulnerabilities in 
        various Mozilla products, the most serious of which allow the 
        remote execution of arbitrary code.


IMPACT: 

        The following vulnerabilities exist in Mozilla products:

          o MFSA-2007-12 (CVE-2007-2867, CVE-2007-2868) describes several 
            stability bug fixes, some of which result in memory corruption 
            and the potential to execute arbitrary code.

          o MFSA-2007-13 (CVE-2007-2869) describes a denial of service 
            vulnerability in Firefox which may be triggered by visiting a 
            malicious web page.

          o MFSA-2007-14 (CVE-2007-1362) describes two vulnerabilities in 
            the way Firefox and SeaMonkey handle cookies with the potential 
            to cause a denial of service.

          o MFSA-2007-15 (CVE-2007-1558) describes a vulnerability in 
            Thunderbird and SeaMonkey APOP authentication functionality 
            which may allow disclosure of the first part of APOP password
            if connecting to a malicious mail server.

          o MFSA-2007-16 (CVE-2007-2870) describes a cross site scripting
            vulnerability in the addEventListener function of Firefox and 
            SeaMonkey.

          o MFSA-2007-17 (CVE-2007-2871) describes a vulnerability in 
            Firefox and SeaMonkey which allows XUL popups to be spoofed, 
            providing misleading infomation to the user.


MITIGATION:

        The above mentioned vulnerabilities have been corrected by new 
        releases of Mozilla Firefox, Thunderbird and Seamonkey. Users of 
        these products are encouraged to upgrade to these new releases, 
        which are available from the Mozilla web site [1]. 

        Mitigation strategies have been identified for some, but not all 
        vulnerabilities.
