CVE-2015-0832

Mozilla Firefox anterior a 36.0 no reconoce correctamente la equivalencia de los nombres de dominios con y sin un caracter . (punto) final, lo que permite a atacantes man-in-the-middle evadir los mecanismos de protección HPKP y HSTS mediante la construcción de una URL con este caracter y el aprovechamiento del acceso a un certificado X.509 para un dominio con este caracter.

USN-2505-1 fixed vulnerabilities in Firefox. This update removed the deprecated "-remote" command-line switch that some older software still depends on. This update fixes the problem. Matthew Noorenberghe discovered that whitelisted Mozilla domains could make UITour API calls from background tabs. If one of these domains were compromised and open in a background tab, an attacker could potentially exploit this to conduct clickjacking attacks. Jan de Mooij discovered an issue that affects content using the Caja Compiler. If web content loads specially crafted code, this could be used to bypass sandboxing security measures provided by Caja. Armin Razmdjou discovered that opening hyperlinks with specific mouse and key combinations could allow a Chrome privileged URL to be opened without context restrictions being preserved. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass security restrictions. Various other issues were also addressed.
