Description :

Jesse Ruderman, Josh Soref, Martijn Wargers, Jose Angel, Olli Pettay,
and David James discovered several flaws 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-2009-3979, CVE-2009-3981, CVE-2009-3986)

Takehiro Takahashi discovered flaws in the NTLM implementation in
Firefox. If an NTLM authenticated user visited a malicious website, a
remote attacker could send requests to other applications,
authenticated as the user. (CVE-2009-3983)

Jonathan Morgan discovered that Firefox did not properly display SSL
indicators under certain circumstances. This could be used by an
attacker to spoof an encrypted page, such as in a phishing attack.
(CVE-2009-3984)

Jordi Chancel discovered that Firefox did not properly display invalid
URLs for a blank page. If a user were tricked into accessing a
malicious website, an attacker could exploit this to spoof the
location bar, such as in a phishing attack. (CVE-2009-3985).
