  script_tag(name:"insight", value:"Several flaws were discovered in the browser and JavaScript engines of
Firefox. If a user were tricked into viewing a malicious website, a remote
attacker could cause a denial of service or possibly execute arbitrary code
with the privileges of the user invoking the program. (CVE-2009-1392,
CVE-2009-1832, CVE-2009-1833, CVE-2009-1837, CVE-2009-1838)

Pavel Cvrcek discovered that Firefox would sometimes display certain
invalid Unicode characters as whitespace. An attacker could exploit this to
spoof the location bar, such as in a phishing attack. (CVE-2009-1834)

Gregory Fleischer, Adam Barth and Collin Jackson discovered that Firefox
would allow access to local files from resources loaded via the file:
protocol. If a user were tricked into downloading then opening a malicious
file, an attacker could steal potentially sensitive information.
(CVE-2009-1835, CVE-2009-1839)

Shuo Chen, Ziqing Mao, Yi-Min Wang, and Ming Zhang discovered that Firefox
did not properly handle error responses when connecting to a proxy server.
If a remote attacker were able to perform a machine-in-the-middle attack, this
flaw could be exploited to view sensitive information. (CVE-2009-1836)

Wladimir Palant discovered Firefox did not check content-loading policies
when loading external script files into XUL documents. As a result, Firefox
might load malicious content under certain circumstances. (CVE-2009-1840)

It was discovered that Firefox could be made to run scripts with elevated
privileges. If a user were tricked into viewing a malicious website, an
attacker could cause a chrome privileged object, such as the browser
sidebar, to run arbitrary code via interactions with the attacker
controlled website. (CVE-2009-1841)");
