Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated firefox packages that fix several security bugs are now
available for Red Hat Enterprise Linux 5.

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

Mozilla Firefox is an open source Web browser.

Flaws were found in the way Firefox executed malformed JavaScript
code. A malicious web page could cause Firefox to crash or allow
arbitrary code to be executed as the user running Firefox.
(CVE-2007-0775, CVE-2007-0777)

Cross-site scripting (XSS) flaws were found in Firefox. A malicious
web page could display misleading information, allowing a user to
unknowingly divulge sensitive information, such as a password.
(CVE-2006-6077, CVE-2007-0995, CVE-2007-0996)

A flaw was found in the way Firefox processed JavaScript contained in
certain tags. A malicious web page could cause Firefox to execute
JavaScript code with the privileges of the user running Firefox.
(CVE-2007-0994)

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

Certain web content could overlay Firefox user interface elements such
as the hostname and security indicators. A malicious web page could
trick a user into thinking they were visiting a different site.
(CVE-2007-0779)

Two flaws were found in Firefox's displaying of blocked popup windows.
If a user could be convinced to open a blocked popup, it was possible
to read arbitrary local files, or conduct a cross-site scripting
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. A malicious web page could set domain cookies for an arbitrary
site, or possibly perform a cross-site scripting attack.
(CVE-2007-0981)

Users of Firefox are advised to upgrade to this erratum package,
containing Firefox version 1.5.0.10 which is not vulnerable to these
issues.
