Synopsis
Mozilla Firefox 1.0.2 fixes new security vulnerabilities, including the
remote execution of arbitrary code through malicious GIF images or
sidebars.
2.
Impact Information
Background
Mozilla Firefox is the popular next-generation browser from the
Mozilla project.
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
