Igor Bukanov discovered that the JavaScript engine did not properly declare some temporary variables. Under some rare circumstances, a malicious mail with embedded JavaScript could exploit this to execute arbitrary code with the privileges of the user. (CVE-2006-0292, CVE-2006-1742)

The function XULDocument.persist() did not sufficiently validate the names of attributes. An attacker could exploit this to inject arbitrary XML code into the file 'localstore.rdf', which is read and evaluated at startup. This could include JavaScript commands that would be run with the user's privileges. (CVE-2006-0296)

Due to a flaw in the HTML tag parser a specific sequence of HTML tags caused memory corruption. A malicious HTML email could exploit this to crash the browser or even execute arbitrary code with the user's privileges. (CVE-2006-0748)

An invalid ordering of table-related tags caused Thunderbird to use a negative array index. A malicious HTML email could exploit this to execute arbitrary code with the privileges of the user.
(CVE-2006-0749)

Georgi Guninski discovered that forwarding mail in-line while using the default HTML 'rich mail' editor executed JavaScript embedded in the email message. Forwarding mail in-line is not the default setting but it is easily accessed through the 'Forward As' menu item.
(CVE-2006-0884)

As a privacy measure to prevent senders (primarily spammers) from tracking when email is read Thunderbird does not load remote content referenced from an HTML mail message until a user tells it to do so.
This normally includes the content of frames and CSS files. It was discovered that it was possible to bypass this restriction by indirectly including remote content through an intermediate inline CSS script or frame. (CVE-2006-1045)

Georgi Guninski discovered that embedded XBL scripts could escalate their (normally reduced) privileges to get full privileges of the user if the email is viewed with 'Print Preview'. (CVE-2006-1727)

The crypto.generateCRMFRequest() function had a flaw which could be exploited to run arbitrary code with the user's privileges.
(CVE-2006-1728)

An integer overflow was detected in the handling of the CSS property 'letter-spacing'. A malicious HTML email 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 email with embedded JavaScript code 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 email 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 email containing JavaScript code could exploit this to execute arbitrary 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 email could exploit this to execute arbitrary JavaScript code with the user's privileges. (CVE-2006-1735)

Several crashes have been fixed which could be triggered by specially crafted HTML content 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)

The 'enigmail' plugin has been updated to work with the new Thunderbird and Mozilla versions.

The remote host is affected by the vulnerability described in GLSA-200604-18 (Mozilla Suite: Multiple vulnerabilities)

    Several vulnerabilities were found in Mozilla Suite. Version     1.7.13 was released to fix them.
  Impact :

    A remote attacker could craft malicious web pages or emails that     would leverage these issues to inject and execute arbitrary script code     with elevated privileges, steal local files, cookies or other     information from web pages or emails, and spoof content. Some of these     vulnerabilities might even be exploited to execute arbitrary code with     the rights of the user running the client.
  Workaround :

    There are no known workarounds for all the issues at this time.

This could include JavaScript commands that would be run with the user's privileges. (CVE-2006-0296)

Due to a flaw in the HTML tag parser a specific sequence of HTML tags caused memory corruption. A malicious website could exploit this to crash the browser or even execute arbitrary code with the user's privileges. (CVE-2006-0748)

An invalid ordering of table-related tags caused Mozilla to use a negative array index. A malicious website could exploit this to execute arbitrary code with the privileges of the user.
(CVE-2006-0749)

Georgi Guninski discovered that embedded XBL scripts of websites could escalate their (normally reduced) privileges to get full privileges of the user if that page is viewed with 'Print Preview'. (CVE-2006-1727)

The crypto.generateCRMFRequest() function had a flaw which could be exploited to run arbitrary code with the user's privileges.
(CVE-2006-1728)

Claus Jorgensen and Jesse Ruderman discovered that a text input box could be pre-filled with a filename and then turned into a file-upload control with the contents intact. A malicious website could exploit this to read any local file the user has read privileges for.
(CVE-2006-1729)

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).

A number of vulnerabilities have been discovered in the Mozilla Thunderbird email client that could allow a remote attacker to craft malicious web emails that could take advantage of these issues to execute arbitrary code with elevated privileges, spoof content, and steal local files, or other information. As well, some of these vulnerabilities can be exploited to execute arbitrary code with the privileges of the user running the program.

As well, two crasher bugs have been fixed as well.

The updated packages have been patched to fix these problems.

Web pages with extremely long titles caused subsequent launches of Firefox browser to hang for up to a few minutes, or caused Firefox to crash on computers with insufficient memory. (CVE-2005-4134)
