bypassed. If a user were tricked into opening a malicious website, an
attacker may be able to execute JavaScript in the context of a
different website. (CVE-2008-3835)

Several problems were discovered in the JavaScript engine. This could
allow an attacker to execute scripts from page content with chrome
privileges. (CVE-2008-3836)
