Mozilla Security Advisory MSA05-011
Title: Mail responds to cookie requests
Reporter: Michiel van Leeuwen
Fixed in: Thunderbird 1.0
Mozilla Suite 1.7.5
Vulnerable: Thunderbird 0.6 - 0.9
Mozilla Suite 1.7 - 1.7.3
Mozilla mail clients from March to December 2004 responded to cookie
requests accompanying content loaded over HTTP, ignoring the setting
of the preference "network.cookie.disableCookieForMailNews" (disabled
cookies are the default in mail).
Cookies in mail (especially spam) could be used to track people.
Set the mail client not to load remote content at all (the default
setting in Thunderbird, the "View as Simple text" option in the Mozilla Suite).
