Vulnerability Assessment Summary
Mozilla Firefox, Mozilla Suite: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200504-18
(Mozilla Firefox, Mozilla Suite: Multiple vulnerabilities)


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 (CVE-2005-0989).
moz_bug_r_a4 discovered that Chrome
UI code was overly trusting DOM nodes from the content window, permiting
privilege escalation via DOM property overrides.
Michael Krax
reported a possibility to run JavaScript code with elevated rights
through the use of javascript: favicons.
Michael Krax also
discovered that malicious Search tests could run JavaScript in the
context of the displayed page or stealthily replace existing search
tests.
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 rights 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 rights.
Omar Khan
reported that the Plugin Finder Service can be tricked to open
javascript: URLs with elevated rights.

Impact

The various JavaScript execution with elevated rights 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 test abuse can be leveraged in cross-site-scripting
attacks.

Workaround

There is no known workaround at this time.
