Description
A flaw could allow malicious content to bypass intended restrictions,
possibly leading to a cross-site scripting (XSS) attack if a user were
tricked into dropping a "javascript:" link onto a frame. (CVE-2012-0455)
It was found that the home page could be set to a "javascript:" link. If a
user were tricked into setting such a home page by dragging a link to the
home button, it could cause Firefox to repeatedly crash, eventually leading
to arbitrary code execution with the privileges of the user running
Firefox. A similar flaw was found and fixed in Thunderbird. (CVE-2012-0458)
A flaw was found in the way Thunderbird parsed certain, remote content
containing "cssText". Malicious, remote content could cause Thunderbird to
crash or, potentially, execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2012-0459)
It was found that by using the DOM fullscreen API, untrusted content could
bypass the mozRequestFullscreen security protections. Malicious content
could exploit this API flaw to cause user interface spoofing.
(CVE-2012-0460)
A flaw was found in the way Thunderbird handled content with multiple
Content Security Policy (CSP) headers. This could lead to a cross-site
scripting attack if used in conjunction with a website that has a header
injection flaw. (CVE-2012-0451)
