Firefox vulnerabilities

Details
A flaw was discovered in handling of "about:blank" windows used by
addons. A malicious web site could exploit this to modify the contents,
or steal confidential data (such as passwords), of other web pages.
(CVE-2007-3844)
Jesper Johansson discovered that spaces and double-quotes were
not correctly handled when launching external programs. In rare
configurations, after tricking a user into opening a malicious web page,
an attacker could execute helpers with arbitrary arguments with the
user's privileges. (CVE-2007-3845)
