Descriptions
WebExtensions can bypass user prompts to first save and then open an arbitrarily downloaded file. This can result in an executable file running with local user privileges without explicit user consent. This vulnerability affects Firefox < 58.
WebExtensions puede omitir los mensajes de diálogo del usuario para primero guardar y luego abrir un archivo descargado arbitrariamente. Esto puede resultar en la ejecución de un archivo ejecutable con privilegios de usuario locales sin el consentimiento explícito del usuario. Esta vulnerabilidad afecta a las versiones anteriores a la 58 de Firefox.
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, spoof the origin in audio capture prompts, trick the user in to providing HTTP credentials for another origin, spoof the addressbar contents, or execute arbitrary code. Various other issues were also addressed.
