The Add-on SDK in Mozilla Firefox before 42.0 misinterprets a "script: false" panel setting, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via inline JavaScript code that is executed within a third-party extension.
El Add-on SDK en Mozilla Firefox en versiones anteriores a 42.0 malinterpreta un 'script: false' en la configuración del panel, lo que hace que sea más fácil para atacantes remotos realizar ataques de cross-site scripting (XSS) a través de código JavaScript inline que se ejecuta dentro de una extensión de terceros.
Christian Holler, David Major, Jesse Ruderman, Tyson Smith, Boris Zbarsky, Randell Jesup, Olli Pettay, Karl Tomlinson, Jeff Walden, Gary Kwong, Andrew McCreight, Georg Fritzsche, and Carsten Book discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. Various other issues were also addressed.
