browsers how safe

zombie · 03-31-2005, 08:55 AM

I'm doing an assisgnment for school about how safe the internet browsers are

Where would i find infomation about the exploits of Internet explorer, Firefox,
Opera & Netscape or good & bad of each browser & why ?

I know this may be a hard question/s but need the research.

Any Sites, docs would be helpful

Thx

There are some institutes, or some thing like that, that record flaws and stuff. I think CAN is one of them. Below you find a copy of a security notification for Firefox on the Gentoo Mailing Lists (the links section might be the most interesting for you):

Severity: Normal
Title: Mozilla Firefox: Multiple vulnerabilities
Date: March 25, 2005
Bugs: #86148
ID: 200503-31

Synopsis
========

Mozilla Firefox 1.0.2 fixes new security vulnerabilities, including the
remote execution of arbitrary code through malicious GIF images or
sidebars.

Background
==========

Mozilla Firefox is the popular next-generation browser from the Mozilla
project.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/mozilla-firefox < 1.0.2 >= 1.0.2
2 www-client/mozilla-firefox-bin < 1.0.2 >= 1.0.2
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
===========

The following vulnerabilities were found and fixed in Mozilla Firefox:

* Mark Dowd from ISS X-Force reported an exploitable heap overrun in
the GIF processing of obsolete Netscape extension 2 (CAN-2005-0399)

* Kohei Yoshino discovered that a page bookmarked as a sidebar could
bypass privileges control (CAN-2005-0402)

* Michael Krax reported a new way to bypass XUL security restrictions
through drag-and-drop of items like scrollbars (CAN-2005-0401)

Impact
======

* The GIF heap overflow could be triggered by a malicious GIF image
that would end up executing arbitrary code with the rights of the
user running Firefox

* By tricking the user into bookmarking a malicious page as a
Sidebar, a remote attacker could potentially execute arbitrary code
with the rights of the user running the browser

* By setting up a malicious website and convincing users to obey very
specific drag-and-drop instructions, attackers may leverage
drag-and-drop features to bypass XUL security restrictions, which
could be used as a stepping stone to exploit other vulnerabilities

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Mozilla Firefox users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.0.2"

All Mozilla Firefox binary users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=www-client/mozilla-firefox-bin-1.0.2"

When concerned with the security of a product, head over to Secunia.

http://secunia.com/

Internet Explorer has 136 vulnerabilities, Firefox has 39, Netscape has 44, Opera has (Get this!) 159, Lynx has 11, et cetera.
