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

This update has been rated as having important security impact by the Red

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 rights, allowing
access to protected data and functions. The Common Vulnerabilities and
Exposures project ( 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.
