1. Summary:
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.

3. Problem description:
Mozilla Firefox is an open source Web browser.
Two flaws were found in the way Firefox processed certain regular
expressions. A malicious web page could crash the browser or possibly
execute arbitrary code as the user running Firefox. (CVE-2006-4565,
CVE-2006-4566)
A number of flaws were found in Firefox. A malicious web page could crash
the browser or possibly execute arbitrary code as the user running Firefox.
(CVE-2006-4571)
A flaw was found in the handling of Javascript timed events. A malicious
web page could crash the browser or possibly execute arbitrary code as the
user running Firefox. (CVE-2006-4253)
Daniel Bleichenbacher recently described an implementation error in RSA
signature verification. For RSA keys with exponent 3 it is possible for an
attacker to forge a signature that would be incorrectly verified by the NSS
library. Firefox as shipped trusts several root Certificate Authorities
that use exponent 3. An attacker could have created a carefully crafted
SSL certificate which be incorrectly trusted when their site was visited by
a victim. (CVE-2006-4340)
A flaw was found in the Firefox auto-update verification system. An
attacker who has the ability to spoof a victim's DNS could get Firefox to
download and install malicious code. In order to exploit this issue an
attacker would also need to get a victim to previously accept an
unverifiable certificate. (CVE-2006-4567)
Firefox did not properly prevent a frame in one domain from injecting
content into a sub-frame that belongs to another domain, which facilitates
website spoofing and other attacks (CVE-2006-4568)
Firefox did not load manually opened, blocked popups in the right domain
context, which could lead to cross-site scripting attacks. In order to
exploit this issue an attacker would need to find a site which would frame
their malicious page and convince the user to manually open a blocked
popup. (CVE-2006-4569)
Users of Firefox are advised to upgrade to this update, which contains
Firefox version 1.5.0.7 that corrects these issues.
