Critical: firefox security update

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.

Mozilla Firefox is an open source Web browser.

Several flaws were found in the way Firefox processes certain malformed
Javascript code. A malicious web page could cause the execution of
Javascript code in such a way that could cause Firefox to crash or execute
arbitrary code as the user running Firefox. (CVE-2006-6498, CVE-2006-6501,
CVE-2006-6502, CVE-2006-6503, CVE-2006-6504)

Several flaws were found in the way Firefox renders web pages. A malicious
web page could cause the browser to crash or possibly execute arbitrary
code as the user running Firefox. (CVE-2006-6497)

Users of Firefox are advised to upgrade to these erratum packages, which
contain Firefox version 1.5.0.9 that corrects these issues.

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

This update is available via Red Hat Network. To use Red Hat Network,
