The InstallTrigger.install method in Firefox before 1.0.5 and Mozilla before 1.7.9 allows remote attackers to execute a callback function in the context of another domain by forcing a page navigation after the install method has been called, which causes the callback to be run in the context of the new page and results in a same origin violation.

An updated firefox package that fixes various security bugs is now available for Red Hat Enterprise Linux 4.

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

Mozilla Firefox is an open source Web browser.

A bug was found in the way Firefox handled synthetic events. It is possible that Web content could generate events such as keystrokes or mouse clicks that could be used to steal data or execute malicious JavaScript code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2260 to this issue.

A bug was found in the way Firefox executed JavaScript in XBL controls. It is possible for a malicious webpage to leverage this vulnerability to execute other JavaScript based attacks even when JavaScript is disabled. (CVE-2005-2261)

A bug was found in the way Firefox set an image as the desktop wallpaper. If a user chooses the 'Set As Wallpaper...' context menu item on a specially crafted image, it is possible for an attacker to execute arbitrary code on a victim's machine. (CVE-2005-2262)

A bug was found in the way Firefox installed its extensions. If a user can be tricked into visiting a malicious webpage, it may be possible to obtain sensitive information such as cookies or passwords.
(CVE-2005-2263)

A bug was found in the way Firefox handled the _search target. It is possible for a malicious website to inject JavaScript into an already open webpage. (CVE-2005-2264)

A bug was found in the way Firefox handled certain JavaScript functions. It is possible for a malicious web page to crash the browser by executing malformed JavaScript code. (CVE-2005-2265)

A bug was found in the way Firefox handled multiple frame domains. It is possible for a frame as part of a malicious website to inject content into a frame that belongs to another domain. This issue was previously fixed as CVE-2004-0718 but was accidentally disabled.
(CVE-2005-1937)

A bug was found in the way Firefox handled child frames. It is possible for a malicious framed page to steal sensitive information from its parent page. (CVE-2005-2266)

A bug was found in the way Firefox opened URLs from media players. If a media player opens a URL that is JavaScript, JavaScript is executed with access to the currently open webpage. (CVE-2005-2267)

A design flaw was found in the way Firefox displayed alerts and prompts. Alerts and prompts were given the generic title [JavaScript Application] which prevented a user from knowing which site created them. (CVE-2005-2268)

A bug was found in the way Firefox handled DOM node names. It is possible for a malicious site to overwrite a DOM node name, allowing certain privileged chrome actions to execute the malicious JavaScript.
(CVE-2005-2269)

A bug was found in the way Firefox cloned base objects. It is possible for Web content to navigate up the prototype chain to gain access to privileged chrome objects. (CVE-2005-2270)

Users of Firefox are advised to upgrade to this updated package that contains Firefox version 1.0.6 and is not vulnerable to these issues.

Updated mozilla packages that fix various security issues 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.

A bug was found in the way Mozilla handled synthetic events. It is possible that Web content could generate events such as keystrokes or mouse clicks that could be used to steal data or execute malicious JavaScript code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-2260 to this issue.

A bug was found in the way Mozilla executed JavaScript in XBL controls. It is possible for a malicious webpage to leverage this vulnerability to execute other JavaScript based attacks even when JavaScript is disabled. (CVE-2005-2261)

A bug was found in the way Mozilla installed its extensions. If a user can be tricked into visiting a malicious webpage, it may be possible to obtain sensitive information such as cookies or passwords.
(CVE-2005-2263)

(CVE-2005-1937)

A bug was found in the way Mozilla handled child frames. It is possible for a malicious framed page to steal sensitive information from its parent page. (CVE-2005-2266)

A bug was found in the way Mozilla opened URLs from media players. If a media player opens a URL which is JavaScript, the JavaScript executes with access to the currently open webpage. (CVE-2005-2267)

A design flaw was found in the way Mozilla displayed alerts and prompts. Alerts and prompts were given the generic title [JavaScript Application] which prevented a user from knowing which site created them. (CVE-2005-2268)

A bug was found in the way Mozilla handled DOM node names. It is possible for a malicious site to overwrite a DOM node name, allowing certain privileged chrome actions to execute the malicious JavaScript.
(CVE-2005-2269)

A bug was found in the way Mozilla cloned base objects. It is possible for Web content to traverse the prototype chain to gain access to privileged chrome objects. (CVE-2005-2270)

Users of Mozilla are advised to upgrade to these updated packages, which contain Mozilla version 1.7.10 and are not vulnerable to these issues.

Secunia.com reported that one of the recent security patches in Firefox reintroduced the frame injection patch that was originally known as CAN-2004-0718. This allowed a malicious website to spoof the contents of other websites. (CAN-2005-1937)

It was discovered that a malicious website could inject arbitrary scripts into a target site by loading it into a frame and navigating back to a previous JavaScript URL that contained an eval() call. This could be used to steal cookies or other confidential data from the target site. (MFSA 2005-42)

Michael Krax, Georgi Guninski, and L. David Baron found that the security checks that prevent script injection could be bypassed by wrapping a javascript: url in another pseudo-protocol like 'view-source:' or 'jar:'. (CAN-2005-1531)

A variant of the attack described in CAN-2005-1160 (see USN-124-1) was discovered. Additional checks were added to make sure JavaScript eval and script objects are run with the privileges of the context that created them, not the potentially elevated privilege of the context calling them. (CAN-2005-1532)

In several places the browser user interface did not correctly distinguish between true user events, such as mouse clicks or keystrokes, and synthetic events genenerated by web content. This could be exploited by malicious websites to generate e. g. mouse clicks that install malicious plugins. Synthetic events are now prevented from reaching the browser UI entirely. (CAN-2005-2260)

Scripts in XBL controls from web content continued to be run even when JavaScript was disabled. This could be combined with most script-based exploits to attack people running vulnerable versions who thought disabling JavaScript would protect them. (CAN-2005-2261)

Matthew Mastracci discovered a flaw in the addons installation launcher. By forcing a page navigation immediately after calling the install method a callback function could end up running in the context of the new page selected by the attacker. This callback script could steal data from the new page such as cookies or passwords, or perform actions on the user's behalf such as make a purchase if the user is already logged into the target site. However, the default settings allow only http://addons.mozilla.org to bring up this install dialog.
This could only be exploited if users have added untrustworthy sites to the installation whitelist, and if a malicious site can convince you to install from their site. (CAN-2005-2263)

The function for version comparison in the addons installer did not properly verify the type of its argument. By passing specially crafted JavaScript objects to it, a malicious website could crash the browser and possibly even execute arbitrary code with the privilege of the user account Firefox runs in. (CAN-2005-2265)

A child frame can call top.focus() even if the framing page comes from a different origin and has overridden the focus() routine. Andreas Sandblad discovered that the call is made in the context of the child frame. This could be exploited to steal cookies and passwords from the framed page, or take actions on behalf of a signed-in user. However, websites with above properties are not very common. (CAN-2005-2266)

Alerts and prompts created by scripts in web pages were presented with the generic title [Javascript Application] which sometimes made it difficult to know which site created them. A malicious page could exploit this by causing a prompt to appear in front of a trusted site in an attempt to extract information such as passwords from the user.
In the fixed version these prompts contain the hostname of the page which created it. (CAN-2005-2268)

The XHTML DOM node handler did not take namespaces into account when verifying node types based on their names. For example, an XHTML document could contain an <IMG> tag with malicious contents, which would then be processed as the standard trusted HTML <img> tag. By tricking an user to view malicious websites, this could be exploited to execute attacker-specified code with the full privileges of the user. (CAN-2005-2269)

It was discovered that some objects were not created appropriately.
This allowed malicious web content scripts to trace back the creation chain until they found a privileged object and execute code with higher privileges than allowed by the current site. (CAN-2005-2270)

The update for Ubuntu 4.10 (Warty Warthog) also fixes several vulnerabilities which are not present in the Ubuntu 5.04 version. 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-2005-41; please see the following website for details:
http://www.mozilla.org/projects/security/known-vulnerabilities.html).
We apologize for the huge delay of this update; we changed our update strategy for Mozilla products to make sure that such long delays will not happen again.

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.

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

Kohei Yoshino discovered a JavaScript injection vulnerability in the sidebar. Sites can use the _search target to open links in the Firefox sidebar. A missing security check allowed the sidebar to inject 'data:' URLs containing scripts into any page open in the browser.
This could be used to steal cookies, passwords or other sensitive data. (CAN-2005-2264)

The function for version comparison in the addons installer did not properly verify the type of its argument. By passing specially crafted JavaScript objects to it, a malicious website could crash the browser and possibly even execute arbitrary code with the privilege of the user account Firefox runs in.

(CAN-2005-2266)

Several media players, for example Flash and QuickTime, support scripted content with the ability to open URLs in the default browser.
The default behavior for Firefox was to replace the currently open browser window's content with the externally opened content. Michael Krax discovered that if the external URL was a javascript: URL it would run as if it came from the site that served the previous content, which could be used to steal sensitive information such as login cookies or passwords. If the media player content first caused a privileged chrome: url to load then the subsequent javascript: url could execute arbitrary code. (CAN-2005-2267)

Alerts and prompts created by scripts in web pages were presented with the generic title [JavaScript Application] which sometimes made it difficult to know which site created them. A malicious page could exploit this by causing a prompt to appear in front of a trusted site in an attempt to extract information such as passwords from the user.
In the fixed version these prompts contain the hostname of the page which created it. (CAN-2005-2268)

A number of vulnerabilities were reported and fixed in Mozilla 1.7.9.
The following vulnerabilities have been backported and patched for this update :

In several places the browser UI did not correctly distinguish between true user events, such as mouse clicks or keystrokes, and synthetic events genenerated by web content. The problems ranged from minor annoyances like switching tabs or entering full-screen mode, to a variant on MFSA 2005-34 Synthetic events are now prevented from reaching the browser UI entirely rather than depend on each potentially spoofed function to protect itself from untrusted events (MFSA 2005-45).

Scripts in XBL controls from web content continued to be run even when JavaScript was disabled. By itself this causes no harm, but it could be combined with most script-based exploits to attack people running vulnerable versions who thought disabling JavaScript would protect them. In the Thunderbird and Mozilla Suite mail clients JavaScript is disabled by default for protection against denial-of-service attacks and worms; this vulnerability could be used to bypass that protection (MFSA 2005-46).

The InstallTrigger.install() method for launching an install accepts a callback function that will be called with the final success or error status. By forcing a page navigation immediately after calling the install method this callback function can end up running in the context of the new page selected by the attacker. This is true even if the user cancels the unwanted install dialog: cancel is an error status. This callback script can steal data from the new page such as cookies or passwords, or perform actions on the user's behalf such as make a purchase if the user is already logged into the target site. In Firefox the default settings allow only http://addons.mozilla.org to bring up this install dialog. This could only be exploited if users have added questionable sites to the install whitelist, and if a malicious site can convince you to install from their site that's a much more powerful attack vector. In the Mozilla Suite the whitelist feature is turned off by default, any site can prompt the user to install software and exploit this vulnerability. The browser has been fixed to clear any pending callback function when switching to a new site (MFSA 2005-48).

When InstallVersion.compareTo() is passed an object rather than a string it assumed the object was another InstallVersion without verifying it. When passed a different kind of object the browser would generally crash with an access violation. shutdown has demonstrated that different JavaScript objects can be passed on some OS versions to get control over the instruction pointer. We assume this could be developed further to run arbitrary machine code if the attacker can get exploit code loaded at a predictable address (MFSA 2005-50).

The original frame-injection spoofing bug was fixed in the Mozilla Suite 1.7 and Firefox 0.9 releases. This protection was accidentally bypassed by one of the fixes in the Firefox 1.0.3 and Mozilla Suite 1.7.7 releases (MFSA 2005-51).

A child frame can call top.focus() even if the framing page comes from a different origin and has overridden the focus() routine. The call is made in the context of the child frame. The attacker would look for a target site with a framed page that makes this call but doesn't verify that its parent comes from the same site. The attacker could steal cookies and passwords from the framed page, or take actions on behalf of a signed-in user. This attack would work only against sites that use frames in this manner (MFSA 2005-52).

Alerts and prompts created by scripts in web pages are presented with the generic title [JavaScript Application] which sometimes makes it difficult to know which site created them. A malicious page could attempt to cause a prompt to appear in front of a trusted site in an attempt to extract information such as passwords from the user. In the fixed version these prompts will contain the hostname from the page which created it (MFSA 2005-54).

Parts of the browser UI relied too much on DOM node names without taking different namespaces into account and verifying that nodes really were of the expected type. An XHTML document could be used to create fake <IMG> elements, for example, with content-defined properties that the browser would access as if they were the trusted built-in properties of the expected HTML elements. The severity of the vulnerability would depend on what the attacker could convince the victim to do, but could result in executing user-supplied script with elevated 'chrome' privileges. This could be used to install malicious software on the victim's machine (MFSA 2005-55).

Improper cloning of base objects allowed web content scripts to walk up the prototype chain to get to a privileged object. This could be used to execute code with enhanced privileges (MFSA 2005-56).

The updated packages have been patched to address these issue. This update also brings the mozilla shipped in Mandriva Linux 10.1 to version 1.7.8 to ease maintenance. As a result, new galeon and epiphany packages are also available for 10.1, and community contribs packages that are built against mozilla have been rebuilt and are also available via contribs.

Several problems have been discovered in Mozilla, the web browser of the Mozilla suite. Since the usual praxis of backporting apparently does not work for this package, this update is basically version 1.7.10 with the version number rolled back, and hence still named 1.7.8. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CAN-2004-0718, CAN-2005-1937     A vulnerability has been discovered in Mozilla that     allows remote attackers to inject arbitrary JavaScript     from one page into the frameset of another site.

  - CAN-2005-2260

    The browser user interface does not properly distinguish     between user-generated events and untrusted synthetic     events, which makes it easier for remote attackers to     perform dangerous actions that normally could only be     performed manually by the user.

  - CAN-2005-2261

    XML scripts ran even when JavaScript disabled.

  - CAN-2005-2263

  - CAN-2005-2268

    It is possible for a JavaScript dialog box to spoof a     dialog box from a trusted site and facilitates phishing     attacks.

  - CAN-2005-2269

    Remote attackers could modify certain tag properties of     DOM nodes that could lead to the execution of arbitrary     script or code.

  - CAN-2005-2270

    The Mozilla browser family does not properly clone base     objects, which allows remote attackers to execute     arbitrary code.

We experienced that the update for Mozilla Firefox from DSA 779-1 unfortunately was a regression in several cases.  Since the usual praxis of backporting apparently does not work, this update is basically version 1.0.6 with the version number rolled back, and hence still named 1.0.4-*.  For completeness below is the original advisory text :

  Several problems have been discovered in Mozilla Firefox, a   lightweight web browser based on Mozilla. The Common Vulnerabilities   and Exposures project identifies the following problems :
