Descriptions
A mechanism to bypass Content Security Policy (CSP) protections on sites that have a "script-src" policy of "'strict-dynamic'". If a target website contains an HTML injection flaw an attacker could inject a reference to a copy of the "require.js" library that is part of Firefox's Developer Tools, and then use a known technique using that library to bypass the CSP restrictions on executing injected scripts. This vulnerability affects Firefox < 60.
Un mecanismo para omitir las protecciones de la Política de Seguridad de Contenidos (CSP) en sitios que tienen una política "script-src" de "strict-dynamic". Si un sitio web objetivo contiene una vulnerabilidad de inyección HTML, el atacante podría inyectar una referencia a una copia de la librería "require.js" que forma parte de las herramientas de desarrollo de Firefox y, a continuación, utilizar una técnica conocida que utilice dicha librería para omitir las restricciones del CSP sobre la ejecución de scripts inyectados. Esta vulnerabilidad afecta a las versiones anteriores a la 60 de Firefox.
USN-3645-1 fixed vulnerabilities in Firefox. The update caused an issue where users experienced long UI pauses in some circumstances. This update fixes the problem. Multiple security issues were discovered 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, bypass same-origin restrictions, conduct cross-site scripting attacks, install lightweight themes without user interaction, spoof the filename in the downloads panel, or execute arbitrary code. Various other issues were also addressed.
