The remote host is affected by the vulnerability described in GLSA-200503-10 (Mozilla Firefox: Various vulnerabilities)

    The following vulnerabilities were found and fixed in Mozilla     Firefox:
    Michael Krax reported that plugins can be used     to load privileged content and trick the user to interact with it     (CAN-2005-0232, CAN-2005-0527)     Michael Krax also reported     potential spoofing or cross-site-scripting issues through overlapping     windows, image drag-and-drop, and by dropping javascript: links on tabs     (CAN-2005-0230, CAN-2005-0231, CAN-2005-0591)     Daniel de Wildt     and Gael Delalleau discovered a memory overwrite in a string library     (CAN-2005-0255)     Wind Li discovered a possible heap overflow in     UTF8 to Unicode conversion (CAN-2005-0592)     Eric Johanson     reported that Internationalized Domain Name (IDN) features allow     homograph attacks (CAN-2005-0233)     Mook, Doug Turner, Kohei     Yoshino and M. Deaudelin reported various ways of spoofing the SSL     'secure site' indicator (CAN-2005-0593)     Matt Brubeck reported     a possible Autocomplete data leak (CAN-2005-0589)     Georgi     Guninski discovered that XSLT can include stylesheets from arbitrary     hosts (CAN-2005-0588)     Secunia discovered a way of injecting     content into a popup opened by another website (CAN-2004-1156)     Phil Ringnalda reported a possible way to spoof Install source with     user:pass@host (CAN-2005-0590)     Jakob Balle from Secunia     discovered a possible way of spoofing the Download dialog source     (CAN-2005-0585)     Christian Schmidt reported a potential     spoofing issue in HTTP auth prompt tab (CAN-2005-0584)     Andreas     Sanblad from Secunia discovered a possible way of spoofing the Download     dialog using the Content-Disposition header (CAN-2005-0586)     Finally, Tavis Ormandy of the Gentoo Linux Security Audit Team     discovered that Firefox insecurely creates temporary filenames in     /tmp/plugtmp (CAN-2005-0578)   Impact :

    By setting up malicious websites and convincing users to     follow untrusted links or obey very specific drag-and-drop or download     instructions, attackers may leverage the various spoofing issues to     fake other websites to get access to confidential information, push     users to download malicious files or make them interact with their     browser preferences.
    The temporary directory issue allows     local attackers to overwrite arbitrary files with the rights of another     local user.
    The overflow issues, while not thought to be     exploitable, may allow a malicious downloaded page to execute arbitrary     code with the rights of the user viewing the page.
  Workaround :

    There is no known workaround at this time.

The installed version of Firefox is earlier than 1.0.1.  Such versions have multiple security issues, including vulnerabilities that could allow an attacker to impersonate a website by using an International Domain Name, or vulnerabilities that could allow arbitrary code execution.

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.

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 CVE-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. (CVE-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. (CVE-2005-0232 and CVE-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. (CVE-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.
(CVE-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.
(CVE-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. (CVE-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. (CVE-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. (CVE-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 website to steal information by tricking a user into arrowing through autocompletion choices. (CVE-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.
(CVE-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. (CVE-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. (CVE-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. (CVE-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. (CVE-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.

USN-149-1 fixed some vulnerabilities in the Ubuntu 5.04 (Hoary Hedgehog) version of Firefox. The version shipped with Ubuntu 4.10 (Warty Warthog) is also vulnerable to these flaws, so it needs to be upgraded as well. Please see

http://www.ubuntulinux.org/support/documentation/usn/usn-149-1

for the original advisory.

This update also fixes several older vulnerabilities; Some of them could be exploited to execute arbitrary code with full user privileges if the user visited a malicious website. (MFSA-2005-01 to MFSA-2005-44; please see the following website for details:
http://www.mozilla.org/projects/security/known-vulnerabilities.html)

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is using Firefox. The remote version of this software contains the following security flaws: 
1) There is a flaw in the way that the browser handle scripting within 'tabbed' cross-domains.  An attacker exploiting this flaw would need to be able to coerce a user into clicking on a malicious URL which would then open a separate 'TAB' within the browser.  The attacker could then retrieve data relevant to other tabbed connections or execute code locally.
2)There is a flaw in the default about: config script that would allow an attacker to modify configuration data. In order to execute such an attack, the attacker would need to be able to entice the user into visiting or clicking on a malicious URL.  A successful attacker would be able to modify the local configuration file, resulting in enhanced access rights or other potential exploits.
