Fedora Core 6: 2007-549 Critical: Firefox JavaScript Issues

epiphany is a simple GNOME web browser based on the Mozilla rendering

engine

Updated firefox packages that fix several security bugs are

now available Fedora Core 6.

This update has been rated as having critical security

impact by the Fedora Security Response Team.

Mozilla Firefox is an open source Web browser.

Several flaws were found in the way Firefox processed

certain malformed JavaScript code. A web page containing

malicious JavaScript code could cause Firefox to crash or

potentially execute arbitrary code as the user running

Firefox. (CVE-2007-2867, CVE-2007-2868)

A flaw was found in the way Firefox handled certain FTP PASV

commands. A malicious FTP server could use this flaw to

perform a rudimentary port-scan of machines behind a user's

firewall. (CVE-2007-1562)

Several denial of service flaws were found in the way

Firefox handled certain form and cookie data. A malicious

web site that is able to set arbitrary form and cookie data

could prevent Firefox from functioning properly.

(CVE-2007-1362, CVE-2007-2869)

A flaw was found in the way Firefox handled the

addEventListener JavaScript method. A malicious web site

could use this method to access or modify sensitive data

from another web site. (CVE-2007-2870)

A flaw was found in the way Firefox displayed certain web

content. A malicious web page could generate content that

would overlay user interface elements such as the hostname

and security indicators, tricking users into thinking they

are visiting a different site. (CVE-2007-2871)

Users of Firefox are advised to upgrade to these erratum

packages, which contain Firefox version 1.5.0.12 that

corrects these issues.
