SecurityTracker Alert ID:  1019351
SecurityTracker URL:  http://securitytracker.com/id/1019351
CVE Reference:   CVE-2008-0418   (Links to External Site)
Date:  Feb 8 2008
Impact:   Disclosure of system information, Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 2.0.0.12
Description:   A vulnerability was reported in Mozilla Firefox when certain add-ons have been installed. A remote user can cause files on the target user's system to be loaded.

A remote user can create specially crafted HTML that, when loaded by the target user, will exploit a flaw in the 'chrome:' URI scheme to load JavaScript, images, and stylesheets from known files on the target user's system. The system is affected only if add-ons that use "flat" packaging (instead of ".jar" packaging) have been used.

This vulnerability can be exploited to obtain the contents of the 'sessionstore.js' file, which includes session cookie data and other potentially sensitive information.

Gerry Eisenhaur and moz_bug_r_a4 reported this vulnerability.
Impact:   A remote user can create HTML that, when loaded by the target user, will load known files on the target user's system.
Solution:   Red Hat has released a fix.

The Red Hat advisory is available at:

3. Description:

Mozilla Firefox is an open source Web browser.

Several flaws were found in the way Firefox processed certain malformed web
content. A webpage containing malicious content could cause Firefox to
crash, or potentially execute arbitrary code as the user running Firefox.
(CVE-2008-0412, CVE-2008-0413, CVE-2008-0415, CVE-2008-0419)

Several flaws were found in the way Firefox displayed malformed web
content. A webpage containing specially-crafted content could trick a user
into surrendering sensitive information. (CVE-2008-0591, CVE-2008-0593)

A flaw was found in the way Firefox stored password data. If a user saves
login information for a malicious website, it could be possible to corrupt
the password database, preventing the user from properly accessing saved
password data. (CVE-2008-0417)

A flaw was found in the way Firefox handles certain chrome URLs. If a user
has certain extensions installed, it could allow a malicious website to
steal sensitive session data. Note: this flaw does not affect a default
installation of Firefox. (CVE-2008-0418)

A flaw was found in the way Firefox saves certain text files. If a
website offers a file of type "plain/text", rather than "text/plain",
Firefox will not show future "text/plain" content to the user in the
browser, forcing them to save those files locally to view the content.
(CVE-2008-0592) 

Users of firefox are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
