Updated firefox packages that fix several security bugs are now available
for Red Hat Enterprise Linux 4.

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

3. Problem description:

Mozilla Firefox is an open source Web browser.

Several flaws were found in the way Firefox processed certain malformed
JavaScript code. A malicious web page could execute JavaScript code in such
a way that may result in Firefox crashing or executing arbitrary code as
the user running Firefox. (CVE-2007-0775, CVE-2007-0777)

Several cross-site scripting (XSS) flaws were found in the way Firefox
processed certain malformed web pages. A malicious web page could display
misleading information which may result in a user unknowingly divulging
sensitive information such as a password. (CVE-2006-6077, CVE-2007-0995,
CVE-2007-0996)

A flaw was found in the way Firefox cached web pages on the local disk. A
malicious web page may be able to inject arbitrary HTML into a browsing
session if the user reloads a targeted site. (CVE-2007-0778)

A flaw was found in the way Firefox displayed certain web content. A
malicious web page could generate content which could overlay user
interface elements such as the hostname and security indicators, tricking a
user into thinking they are visiting a different site. (CVE-2007-0779)

Two flaws were found in the way Firefox displayed blocked popup windows. If
a user can be convinced to open a blocked popup, it is possible to read
arbitrary local files, or conduct an XSS attack against the user.
(CVE-2007-0780, CVE-2007-0800)

Two buffer overflow flaws were found in the Network Security Services (NSS)
code for processing the SSLv2 protocol. Connecting to a malicious secure
web server could cause the execution of arbitrary code as the user running
Firefox. (CVE-2007-0008, CVE-2007-0009)

A flaw was found in the way Firefox handled the "location.hostname" value
during certain browser domain checks. This flaw could allow a malicious web
site to set domain cookies for an arbitrary site, or possibly perform an
XSS attack. (CVE-2007-0981)

Users of Firefox are advised to upgrade to these erratum packages, which
contain Firefox version 1.5.0.10 that corrects these issues.

4. Solution:

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

5. Bug IDs fixed (http://bugzilla.redhat.com/):

202352 - Firefox 1.5.0.5 startup script not updated for the add-on based locale
229802 - CVE-2007-0775 Multiple Firefox flaws (CVE-2007-0777, CVE-2007-0995, CVE-2007-0996, CVE-2006-6077, CVE-2007-0778, CVE-2007-0779, CVE-2007-0780, CVE-2007-0800, CVE-2007-0008, CVE-2007-0009, CVE-2007-0981)
