Mozilla before 1.7.6, and Firefox before 1.0.1, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability.

Updated Mozilla packages that fix various security bugs are now available.

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

Mozilla is an open source Web browser, advanced email and newsgroup client, IRC chat client, and HTML editor.

Several bugs were found with the way Mozilla displays the secure site icon. It is possible that a malicious website could display the secure site icon along with incorrect certificate information. (CVE-2005-0143 CVE-2005-0593)

A bug was found in the way Mozilla handles synthetic middle click events. It is possible for a malicious web page to steal the contents of a victims clipboard. (CVE-2005-0146)

Several bugs were found with the way Mozilla handles temporary files.
A local user could view sensitive temporary information or delete arbitrary files. (CVE-2005-0142 CVE-2005-0578)

A bug was found in the way Mozilla 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 flaw was found in the way Mozilla 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 Mozilla processes XUL content. If a malicious web page can trick a user into dragging an object, it is possible to load malicious XUL content. (CVE-2005-0401)

A bug was found in the way Mozilla 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)

Several bugs were found in the way Mozilla displays alert dialogs. It is possible for a malicious webserver or website to trick a user into thinking the dialog window is being generated from a trusted site.
(CVE-2005-0586 CVE-2005-0591 CVE-2005-0585 CVE-2005-0590 CVE-2005-0584)

A bug was found in the Mozilla 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 Mozilla 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 bug was found in the way Mozilla handles anonymous functions during regular expression string replacement. It is possible for a malicious web page to capture a random block of browser memory. (CVE-2005-0989)

A bug was found in the way Mozilla displays pop-up windows. If a user choses to open a pop-up window whose URL is malicious JavaScript, the script will be executed with elevated privileges. (CVE-2005-1153)

A bug was found in the way Mozilla installed search plugins. If a user chooses to install a search plugin from a malicious site, the new plugin could silently overwrite an existing plugin. This could allow the malicious plugin to execute arbitrary code and stealm sensitive information. (CVE-2005-1156 CVE-2005-1157)

Several bugs were found in the Mozilla JavaScript engine. A malicious web page could leverage these issues to execute JavaScript with elevated privileges or steal sensitive information. (CVE-2005-1154 CVE-2005-1155 CVE-2005-1159 CVE-2005-1160)

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

A Secunia Research advisory reports :

Secunia Research has reported a vulnerability in multiple browsers, which can be exploited by malicious people to spoof the content of websites.

The problem is that a website can inject content into another site's window if the target name of the window is known. This can e.g. be exploited by a malicious website to spoof the content of a pop-up window opened on a trusted website.

Secunia has constructed a test, which can be used to check if your browser is affected by this issue :

A workaround for Mozilla-based browsers is available.

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.

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.
