The Mozilla Suite is a popular all-in-one web browser that includes a
mail and news reader. Mozilla Firefox is the next-generation browser
from the Mozilla project.
The following vulnerabilities were found and fixed in the Mozilla Suite
and Mozilla Firefox:
- Vladimir V. Perepelitsa reported a memory disclosure bug in
JavaScript's regular expression string replacement when using an
anonymous function as the replacement argument (CAN-2005-0989).
- moz_bug_r_a4 discovered that Chrome UI code was overly trusting DOM
nodes from the content window, allowing privilege escalation via DOM
property overrides.
- Michael Krax reported a possibility to run JavaScript code with
elevated privileges through the use of javascript: favicons.
- Michael Krax also discovered that malicious Search plugins could
run JavaScript in the context of the displayed page or stealthily
replace existing search plugins.
- shutdown discovered a technique to pollute the global scope of a
window in a way that persists from page to page.
- Doron Rosenberg discovered a possibility to run JavaScript with
elevated privileges when the user asks to "Show" a blocked popup that
contains a JavaScript URL.
- Finally, Georgi Guninski reported missing Install object instance
checks in the native implementations of XPInstall-related JavaScript
objects.
The following Firefox-specific vulnerabilities have also been
discovered:
- Kohei Yoshino discovered a new way to abuse the sidebar panel to
execute JavaScript with elevated privileges.
- Omar Khan reported that the Plugin Finder Service can be tricked to
open javascript: URLs with elevated privileges.
The various JavaScript execution with elevated privileges issues can be
exploited by a remote attacker to install malicious code or steal data.
The memory disclosure issue can be used to reveal potentially sensitive
information. Finally, the cache pollution issue and search plugin abuse
can be leveraged in cross-site-scripting attacks.
There is no known workaround at this time.
