Descriptions

Content Security Policy (CSP) is not applied correctly to all parts of multipart content sent with the "multipart/x-mixed-replace" MIME type. This could allow for script to run where CSP should block it, allowing for cross-site scripting (XSS) and other attacks. This vulnerability affects Firefox < 60.

La política de seguridad de contenidos (CSP) no se aplica correctamente a todas las partes del contenido multiparte enviado con el tipo MIME "multipart/x-mixed-replace". Esto podría permitir que el script se ejecute donde el CSP debería bloquearlo, permitiendo Cross-Site Scripting (XSS) y otros ataques. 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.
