The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: mozilla-thunderbird 1.5.0.13+1.5.0.14b-0ubuntu0.6.06 Ubuntu 6.10: mozilla-thunderbird 1.5.0.13+1.5.0.14b-0ubuntu0.6.10 Ubuntu 7.04: mozilla-thunderbird 1.5.0.13+1.5.0.14b-0ubuntu0.7.04 Ubuntu 7.10: mozilla-thunderbird 2.0.0.8~pre071022+nobinonly-0ubuntu0.7.10 After a standard system upgrade you need to restart Thunderbird to affect the necessary changes. Details follow: Various flaws were discovered in the layout and JavaScript engines.

(CVE-2007-5339, CVE-2007-5340) Flaws were discovered in the file upload form control. By tricking a user into opening a malicious web page, an attacker could force arbitrary files from the user's computer to be uploaded without their consent. (CVE-2006-2894, CVE-2007-3511) Michal Zalewski discovered that the onUnload event handlers were incorrectly able to access information outside the old page content. A malicious web site could exploit this to modify the contents, or steal confidential data (such as passwords), of the next loaded web page.

A malicious web site could exploit this to inject arbitrary HTTP headers or perform session splitting attacks against proxies.

(CVE-2007-5334) Georgi Guninski discovered that Thunderbird would allow file-system based web pages to access additional files. By tricking a user into opening a malicious web page from a gnome-vfs location, an attacker could steal arbitrary files from the user's computer. (CVE-2007-5337) It was discovered that the XPCNativeWrappers were not safe in certain situations. By tricking a user into opening a malicious web page, an attacker could run arbitrary JavaScript with the user's privileges.
