(Red Hat Issues Fix for Thunderbird) Mozilla Firefox URL Bug Lets Remote Users Spoof HTTP Referer Values in Certain Cases
SecurityTracker Alert ID:  1019773
SecurityTracker URL:  http://securitytracker.com/id/1019773
CVE Reference:   CVE-2008-1238   (Links to External Site)
Date:  Apr 3 2008
Impact:   Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in Mozilla Firefox. A remote user can spoof the HTTP Referer value in certain cases. Mozilla Thunderbird is affected.

When a request is sent to a URL with Basic Authentication credentials and an empty username value, the browser removes characters from the hostname in the HTTP Referer field. If a target web site relies on the value for security purposes, the remote user may be able to bypass security controls.

Gregory Fleischer reported this vulnerability. RSnake reported the original concept.

Impact:   A remote user can spoof the HTTP Referer value to potentially bypass security controls on the target web site.
Solution:   Red Hat has released a fix for Thunderbird, which is affected by this vulnerability.

The Red Hat advisory is available at:

3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of some malformed HTML mail
content. An HTML mail message containing such malicious content could cause
Thunderbird to crash or, potentially, execute arbitrary code as the user
running Thunderbird. (CVE-2008-1233, CVE-2008-1235, CVE-2008-1236,
CVE-2008-1237)

Several flaws were found in the display of malformed web content. An HTML
mail message containing specially-crafted content could, potentially, trick
a user into surrendering sensitive information. (CVE-2008-1234,
CVE-2008-1238, CVE-2008-1241)

Note: JavaScript support is disabled by default in Thunderbird; the above
issues are not exploitable unless JavaScript is enabled.

All Thunderbird users should upgrade to these updated packages, which
contain backported patches to resolve these issues.
