Description
Calling the QueryInterface method of the built-in
Location and Navigator objects causes memory corruption
that might be exploitable to run arbitrary code.
This flaw appears to have been introduced during development of Firefox 1.5/SeaMonkey 1.0 -- Firefox 1.0 and the older Mozilla Suite 1.7 do not appear to be vulnerable.
Thunderbird 1.5 could be vulnerable if JavaScript is enabled in mail. This is not the default setting and we strongly discourage users from turning on JavaScript in mail. Thunderbird is not vulnerable in its default configuration.
Update (7 February 2006)
H D Moore of the Metasploit Project published a working exploit on milw0rm
for the Linux and Mac OS X versions of Firefox 1.5. Severity upgraded
to critical.
Update (13 April 2006)
This flaw has been fixed in Thunderbird 1.5.0.2
Workaround
Upgrade to the fixed versions. Do not enable JavaScript in Thunderbird or SeaMonkey mail.
