windows. If a user can be convinced to open a blocked popup, it is
possible to read arbitrary local files, or conduct an XSS attack
against the user. (CVE-2007-0780, CVE-2007-0800)
Two buffer overflow flaws were found in the Network Security Services
(NSS) code for processing the SSLv2 protocol. Connecting to a
malicious secure web server could cause the execution of arbitrary
code as the user running Thunderbird. (CVE-2007-0008, CVE-2007-0009)
A flaw was found in the way Thunderbird handled the
'location.hostname' value during certain browser domain checks. This
