An integer overflow was detected in the handling of the CSS property 'letter-spacing'. A malicious website could exploit this to run arbitrary code with the user's privileges. (CVE-2006-1730)

The methods valueOf.call() and .valueOf.apply() returned an object whose privileges were not properly confined to those of the caller, which made them vulnerable to cross-site scripting attacks. A malicious website could exploit this to modify the contents or steal confidential data (such as passwords) from other opened web pages.
(CVE-2006-1731) The window.controllers array variable (CVE-2006-1732) and event handlers (CVE-2006-1741) were vulnerable to a similar attack. 

The privileged built-in XBL bindings were not fully protected from web content and could be accessed by calling valueOf.call() and valueOf.apply() on a method of that binding. A malicious website could exploit this to run arbitrary JavaScript code with the user's privileges. (CVE-2006-1733)

It was possible to use the Object.watch() method to access an internal function object (the 'clone parent'). A malicious website could exploit this to execute arbitrary JavaScript code with the user's privileges. (CVE-2006-1734)

By calling the XBL.method.eval() method in a special way it was possible to create JavaScript functions that would get compiled with the wrong privileges. A malicious website could exploit this to execute arbitrary JavaScript code with the user's privileges.
(CVE-2006-1735)

Michael Krax discovered that by layering a transparent image link to an executable on top of a visible (and presumably desirable) image a malicious site could fool the user to right-click and choose 'Save image as...' from the context menu, which would download the executable instead of the image. (CVE-2006-1736)

Several crashes have been fixed which could be triggered by websites and involve memory corruption. These could potentially be exploited to execute arbitrary code with the user's privileges. (CVE-2006-1737, CVE-2006-1738, CVE-2006-1739, CVE-2006-1790)

If the user has turned on the 'Entering secure site' modal warning dialog, it was possible to spoof the browser's secure-site indicators (the lock icon and the gold URL field background) by first loading the target secure site in a pop-up window, then changing its location to a different site, which retained the displayed secure-browsing indicators from the original site. (CVE-2006-1740).
