Mozilla Firefox is an open source web browser.
Several flaws were found in the processing of malformed web content. A
web page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user
running Firefox. (CVE-2012-0461, CVE-2012-0462, CVE-2012-0464)
Two flaws were found in the way Firefox parsed certain Scalable Vector
Graphics (SVG) image files. A web page containing a malicious SVG
image file could cause an information leak, or cause Firefox to crash
or, potentially, execute arbitrary code with the privileges of the
user running Firefox. (CVE-2012-0456, CVE-2012-0457)
A flaw could allow a malicious site to bypass intended restrictions,
possibly leading to a cross-site scripting (XSS) attack if a user were
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. (CVE-2012-0458)
A flaw was found in the way Firefox parsed certain web content
containing 'cssText'. A web page containing malicious content could
cause Firefox to crash or, potentially, execute arbitrary code with
the privileges of the user running Firefox. (CVE-2012-0459)
It was found that by using the DOM fullscreen API, untrusted content
could bypass the mozRequestFullscreen security protections. A web page
containing malicious web content could exploit this API flaw to cause
user interface spoofing. (CVE-2012-0460)
A flaw was found in the way Firefox handled pages 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)
For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 10.0.3 ESR. You can find a link to the
