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 :

    - 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-2005-2262

      The user can be tricked to executing arbitrary       JavaScript code by using a JavaScript URL as       wallpaper.

    - CAN-2005-2263

      It is possible for a remote attacker to execute a       callback function in the context of another domain       (i.e. frame).

    - CAN-2005-2264

      By opening a malicious link in the sidebar it is       possible for remote attackers to steal sensitive       information.

    - CAN-2005-2265

      Missing input sanitising of InstallVersion.compareTo()       can cause the application to crash.

    - CAN-2005-2266

      Remote attackers could steal sensitive information       such as cookies and passwords from websites by       accessing data in alien frames.

    - CAN-2005-2267

      By using standalone applications such as Flash and       QuickTime to open a javascript: URL, it is possible       for a remote attacker to steal sensitive information       and possibly execute arbitrary code.

    - 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.

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.

The Mozilla Foundation reports of multiple security vulnerabilities in Firefox and Mozilla :

- MFSA 2005-56 Code execution through shared function objects

- MFSA 2005-55 XHTML node spoofing

- MFSA 2005-54 JavaScript prompt origin spoofing

- MFSA 2005-53 Standalone applications can run arbitrary code through the browser

- MFSA 2005-52 Same origin violation: frame calling top.focus()

- MFSA 2005-51 The return of frame-injection spoofing

- MFSA 2005-50 Possibly exploitable crash in InstallVersion.compareTo()

- MFSA 2005-49 Script injection from Firefox sidebar panel using data :

- MFSA 2005-48 Same-origin violation with InstallTrigger callback

- MFSA 2005-47 Code execution via 'Set as Wallpaper'

- MFSA 2005-46 XBL scripts ran even when JavaScript disabled

- MFSA 2005-45 Content-generated event vulnerabilities

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)

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)

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-2005-2265)

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)

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)

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).

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 version of Firefox contains various security issues that may allow an attacker execute arbitrary code on the remote host.

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:
