RedHat: Important: firefox security update

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.

Summary

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 CAN-2005-1476, CAN-2005-1477, CAN-2005-1531, and CAN-2005-1532 to these issues. Please note that the effects of CAN-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.
