OVERVIEW

        Mozilla have released a new version of Thunderbird, correcting a
        critical security vulnerability.


IMPACT

        The vendor has provided the following details regarding this 
        vulnerability which has been assigned CVE-2010-3765:
        
        "Morten Krkvik of Telenor SOC reported an exploit targeting particular 
        versions of Firefox 3.6 on Windows XP that Telenor found while 
        investigating an intrusion attempt on a customer network. The 
        underlying vulnerability, however, was present on both the Firefox 3.5 
        and Firefox 3.6 development branches and affected all supported 
        platforms.
        
        Note: Reading mail in Thunderbird does not pose a risk to users, 
        however the vulnerability is present and could be triggered in RSS 
        feeds if JavaScript is enabled or by an add-on that enables browser-
        like functionality." [1]


MITIGATION

        The latest version of Thunderbird is available for download from
        the vendor's website. [2]
