| Description: | Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.
A flaw was found in Sanitiser for OpenType (OTS), used by Firefox to help prevent potential exploits in malformed OpenType fonts. A web page containing malicious content could cause Firefox to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-3062)
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-2012-0467, CVE-2012-0468, CVE-2012-0469)
A web page containing a malicious Scalable Vector Graphics (SVG) image file could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2012-0470)
A flaw was found in the way Firefox used its embedded Cairo library to render certain fonts. A web page containing malicious content could cause Firefox to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Firefox. (CVE-2012-0472)
A flaw was found in the way Firefox rendered certain images using WebGL. A web page containing malicious content could cause Firefox to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Firefox. (CVE-2012-0478)
A cross-site scripting (XSS) flaw was found in the way Firefox handled certain multibyte character sets. A web page containing malicious content could cause Firefox to run JavaScript code with the permissions of a different website. (CVE-2012-0471)
A flaw was found in the way Firefox rendered certain graphics using WebGL. A web page containing malicious content could cause Firefox to crash. (CVE-2012-0473)
A flaw in Firefox allowed the address bar to display a different website than the one the user was visiting. An attacker could use this flaw to conceal a malicious URL, possibly tricking a user into believing they are viewing a trusted site, or allowing scripts to be loaded from the attacker's site, possibly leading to cross-site scripting (XSS) attacks. (CVE-2012-0474)
A flaw was found in the way Firefox decoded the ISO-2022-KR and ISO-2022-CN character sets. A web page containing malicious content could cause Firefox to run JavaScript code with the permissions of a different website. (CVE-2012-0477)
A flaw was found in the way Firefox handled RSS and Atom feeds. Invalid RSS or Atom content loaded over HTTPS caused Firefox to display the address of said content in the location bar, but not the content in the main window. The previous content continued to be displayed. An attacker could use this flaw to perform phishing attacks, or trick users into thinking they are visiting the site reported by the location bar, when the page is actually content controlled by an attacker. (CVE-2012-0479)
For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 10.0.4 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.
