1. Summary:

Updated firefox packages that fix various bugs are now available.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

Mozilla Firefox is an open source Web browser.

A bug was found in the Firefox string handling functions. If a malicious
website is able to exhaust a system's memory, it becomes possible to
execute arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0255 to this issue.

A bug was found in the way Firefox handles pop-up windows. It is possible
for a malicious website to control the content in an unrelated site's
pop-up window. (CAN-2004-1156)

A bug was found in the way Firefox allows plug-ins to load privileged
content into a frame. It is possible that a malicious webpage could trick a
user into clicking in certain places to modify configuration settings or
execute arbitrary code. (CAN-2005-0232 and CAN-2005-0527).

A flaw was found in the way Firefox displays international domain names. It
is possible for an attacker to display a valid URL, tricking the user into
thinking they are viewing a legitimate webpage when they are not.
(CAN-2005-0233)

A bug was found in the way Firefox handles plug-in temporary files. A
malicious local user could create a symlink to a victims directory, causing
it to be deleted when the victim exits Firefox. (CAN-2005-0578)

A bug has been found in one of Firefox's UTF-8 converters. It may be
possible for an attacker to supply a specially crafted UTF-8 string to the
buggy converter, leading to arbitrary code execution. (CAN-2005-0592)

A bug was found in the Firefox javascript security manager. If a user drags
a malicious link to a tab, the javascript security manager is bypassed
which could result in remote code execution or information disclosure.
(CAN-2005-0231)

A bug was found in the way Firefox displays the HTTP authentication prompt.
When a user is prompted for authentication, the dialog window is displayed
over the active tab, regardless of the tab that caused the pop-up to appear
and could trick a user into entering their username and password for a
trusted site.  (CAN-2005-0584)

A bug was found in the way Firefox displays the save file dialog. It is
possible for a malicious webserver to spoof the Content-Disposition header,
tricking the user into thinking they are downloading a different filetype.
(CAN-2005-0586)

A bug was found in the way Firefox handles users "down-arrow" through auto
completed choices. When an autocomplete choice is selected, the information
is copied into the input control, possibly allowing a malicious web site to
steal information by tricking a user into arrowing through autocompletion
choices. (CAN-2005-0589)

Several bugs were found in the way Firefox displays the secure site icon.
It is possible that a malicious website could display the secure site icon
along with incorrect certificate information. (CAN-2005-0593)

A bug was found in the way Firefox displays the download dialog window. A
malicious site can obfuscate the content displayed in the source field,
tricking a user into thinking they are downloading content from a trusted
source. (CAN-2005-0585)

A bug was found in the way Firefox handles xsl:include and xsl:import
directives. It is possible for a malicious website to import XSLT
stylesheets from a domain behind a firewall, leaking information to an
attacker. (CAN-2005-0588)

A bug was found in the way Firefox displays the installation confirmation
dialog. An attacker could add a long user:pass before the true hostname,
tricking a user into thinking they were installing content from a trusted
source. (CAN-2005-0590)

A bug was found in the way Firefox displays download and security dialogs.
An attacker could cover up part of a dialog window tricking the user into
clicking "Allow" or "Open", which could potentially lead to arbitrary code
execution. (CAN-2005-0591)

Users of Firefox are advised to upgrade to this updated package which
contains Firefox version 1.0.1 and is not vulnerable to these issues.
