Users of Mozilla are advised to upgrade to this updated package which contains Mozilla version 1.7.7 to correct these issues.

Firefoxのインストールバージョンは、1.0.1より前です。このようなバージョンには、攻撃者が国際ドメイン名を使用してWebサイトになりすますことができる脆弱性や、任意コード実行を許してしまう脆弱性など、複数のセキュリティ問題があります。

已安裝的 Firefox 版本比 1.0.1 舊。這些版本含有多個安全性問題，包括可讓攻擊者使用國際網域名稱模擬網站的弱點，或可導致任意程式碼執行的弱點。

已安装的 Firefox 版本低于 1.0.1。此类版本存在多个安全问题，包括可允许攻击者通过使用国际化域名冒充网站的漏洞，或者可允许任意代码执行的漏洞。

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.

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 remote host is affected by the vulnerability described in GLSA-200503-30 (Mozilla Suite: Multiple vulnerabilities)

    The following vulnerabilities were found and fixed in the Mozilla     Suite:
    Mark Dowd from ISS X-Force reported an exploitable     heap overrun in the GIF processing of obsolete Netscape extension 2     (CAN-2005-0399)     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 or scrollbar drag-and-drop, and by dropping javascript:
    links on tabs (CAN-2005-0230, CAN-2005-0231, CAN-2005-0401,     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)     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)     Finally, Tavis Ormandy of the Gentoo Linux Security Audit Team     discovered that Mozilla insecurely creates temporary filenames in     /tmp/plugtmp (CAN-2005-0578)   Impact :

    The GIF heap overflow could be triggered by a malicious GIF     image that would end up executing arbitrary code with the rights of the     user running Mozilla. The other overflow issues, while not thought to     be exploitable, would have the same 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   Workaround :

    There is no known workaround at this time.

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 Redhat Enterprise Linux 4 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2005:176 advisory.

    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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.
