Description Vincent Danen 2010-01-29 23:01:43 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2009-4629 to
the following vulnerability:

Name: CVE-2009-4629
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-4629
Assigned: 20100129
Reference: MISC: https://secure.grepular.com/DNS_Prefetch_Exposure_on_Thunderbird_and_Webmail
Reference: CONFIRM: https://bugzilla.mozilla.org/show_bug.cgi?id=492196

Mozilla Necko, as used in Thunderbird 3.0.1, SeaMonkey, and other
applications, performs DNS prefetching even when the app type is
APP_TYPE_MAIL or APP_TYPE_EDITOR, which makes it easier for remote
attackers to determine the network location of the application's user
by logging DNS requests, as demonstrated by DNS requests triggered by
reading text/plain e-mail messages in Thunderbird.


Note that this issue would not affect Thunderbird or Seamonkey as shipped with Red Hat Enterprise Linux 3, 4, or 5 as DNS prefetching was not implemented in the versions of Thunderbird or Seamonkey provided (no nsHTMLDNSPrefetch.cpp, for instance).  DNS prefetching was implemented in xul-runner 1.9.1 as per https://bugzilla.mozilla.org/show_bug.cgi?id=453403).
