(Red Hat Issues Fix for Thunderbird) Mozilla Firefox Input Validation Hole in jar: Protocol Handler Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1019128
SecurityTracker URL:  http://securitytracker.com/id/1019128
CVE Reference:   CVE-2007-5947   (Links to External Site)
Date:  Dec 19 2007
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in Mozilla Firefox. A remote user can conduct cross-site scripting attacks. Mozilla Thunderbird is affected.

The jar: protocol handler does not properly validate the MIME types of archive contents. A remote user can upload a specially crafted zip file (or certain other files). Then, when the target user loads a jar: URL that points to the zip file, arbitrary scripting code will be executed by the target user's browser. The code will originate from the site permitting the file upload and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Jesse Ruderman, pdp, and beford.org separately reported this vulnerability.

The original reports are available at:

https://bugzilla.mozilla.org/show_bug.cgi?id=369814
http://www.gnucitizen.org/blog/web-mayhem-firefoxs-jar-protocol-issues
Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with an arbitrary site that allows certain types of file uploads, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
Solution:   Red Hat has released a fix for Mozilla Thunderbird, which is affected by this vulnerability.

The Red Hat advisory is available at:

1. Summary:

Updated thunderbird packages that fix several security issues are now
available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64

3. Problem description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

A cross-site scripting flaw was found in the way Thunderbird handled the
jar: URI scheme. It may be possible for a malicious HTML mail message to
leverage this flaw, and conduct a cross-site scripting attack against a
user running Thunderbird. (CVE-2007-5947)

Several flaws were found in the way Thunderbird processed certain malformed
HTML mail content. A HTML mail message containing malicious content could
cause Thunderbird to crash, or potentially execute arbitrary code as the
user running Thunderbird. (CVE-2007-5959)

A race condition existed when Thunderbird set the "window.location"
property when displaying HTML mail content. This flaw could allow a HTML
mail message to set an arbitrary Referer header, which may lead to a
Cross-site Request Forgery (CSRF) attack against websites that rely only on
the Referer header for protection. (CVE-2007-5960) 

All users of thunderbird are advised to upgrade to these updated packages,
which contain backported patches to resolve these issues.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
