RHEL 4 : firefox (RHSA-2005:434)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated firefox packages that fix various security bugs are now
available.

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

Mozilla Firefox is an open source Web browser.

Several bugs were found in the way Firefox executes JavaScript code.
JavaScript executed from a web page should run with a restricted
access level, preventing dangerous actions. It is possible that a
malicious web page could execute JavaScript code with elevated
privileges, allowing access to protected data and functions. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CVE-2005-1476, CVE-2005-1477, CVE-2005-1531, and
CVE-2005-1532 to these issues.

Please note that the effects of CVE-2005-1477 are mitigated by the
default setup, which allows only the Mozilla Update site to attempt
installation of Firefox extensions. The Mozilla Update site has been
modified to prevent this attack from working. If other URLs have been
manually added to the whitelist, it may be possible to execute this
attack.

Users of Firefox are advised to upgrade to this updated package which
contains Firefox version 1.0.4 which is not vulnerable to these
issues.
