CVE-2009-3274
Jeremy Brown discovered that the filename of a downloaded file
which is opened by the user is predictable, which might lead to
tricking the user into a malicious file if the attacker has local
access to the system.

1) Introduction
I want to warn you about Denial of Service vulnerability in Mozilla Firefox,
Internet Explorer and Chrome.
At the end of December DoS vulnerability in Mozilla Firefox 3.0.5 was found
by Jeremy Brown (http://websecurity.com.ua/2755/). After I checked at
23.12.2008 this vulnerability in different browsers (and also yesterday in
new version of Firefox), I found that this Denial of Service vulnerability
also exists in Firefox 3.0.13, Internet Explorer 6 and Chrome 1.0.154.48.
