[GLSA-200505-11] Mozilla Suite, Mozilla Firefox: Remote compromise

Vulnerability Assessment Summary
Mozilla Suite, Mozilla Firefox: Remote compromise

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200505-11
(Mozilla Suite, Mozilla Firefox: Remote compromise)

The Mozilla Suite and Firefox do not properly protect "IFRAME"
JavaScript URLs from being executed in context of another URL in the
history list (CVE-2005-1476). The Mozilla Suite and Firefox also fail
to verify the "IconURL" parameter of the "InstallTrigger.install()"
function (CVE-2005-1477). Michael Krax and Georgi Guninski discovered
that it is possible to bypass JavaScript-injection security checks by
wrapping the javascript: URL within the view-source: or jar:
pseudo-protocols (MFSA2005-43).

Impact

A malicious remote attacker could use the "IFRAME" issue to
execute arbitrary JavaScript code within the context of another
website, permiting to steal cookies or other sensitive data. By
supplying a javascript: URL as the "IconURL" parameter of the
"InstallTrigger.Install()" function, a remote attacker could also
execute arbitrary JavaScript code. Combining both vulnerabilities with
a website which is permited to install software or wrapping javascript:
URLs within the view-source: or jar: pseudo-protocols could possibly
lead to the execution of arbitrary code with user rights.

Workaround

Affected systems can be protected by disabling JavaScript.
However, we encourage Mozilla Suite or Mozilla Firefox users to upgrade
to the latest available version.
