Debian DSA-779-2 : mozilla-firefox - several vulnerabilities

high Nessus Plugin ID 19476
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


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.


Upgrade the Mozilla Firefox packages.

The old stable distribution (woody) is not affected by these problems.

For the stable distribution (sarge) these problems have been fixed in version 1.0.4-2sarge3.
