[DSA779] DSA-779-2 mozilla-firefox

Vulnerability Assessment Summary
DSA-779-2 mozilla-firefox

Detailed Explanation for this Vulnerability Assessment

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
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:
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.
XML scripts ran even when Javascript disabled.
The user can be tricked to executing arbitrary JavaScript code by
using a JavaScript URL as wallpaper.
It is possible for a remote attacker to execute a callback
function in the context of another domain (i.e. frame).
By opening a malicious link in the sidebar it is possible for
remote attackers to steal sensitive information.
Missing input sanitising of InstallVersion.compareTo() can cause
the application to crash.
Remote attackers could steal sensitive information such as cookies
and passwords from web sites by accessing data in alien frames.
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.
It is possible for a Javascript dialog box to spoof a dialog box
from a trusted site and facilitates phishing attacks.
Remote attackers could modify certain tag properties of DOM nodes
that could lead to the execution of arbitrary script or code.
The Mozilla browser family does not properly clone base objects,
which permits remote attackers to execute arbitrary code.
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.
For the unstable distribution (sid) these problems have been fixed in
version 1.0.6-1.
We recommend that you upgrade your Mozilla Firefox packages.
