Descriptions

A Blob URL can violate origin attribute segregation, allowing it to be accessed from a private browsing tab and for data to be passed between the private browsing tab and a normal tab. This could allow for the leaking of private information specific to the private browsing context. This issue is mitigated by the requirement that the user enter the Blob URL manually in order for the access violation to occur. This vulnerability affects Firefox < 58.

Una URL Blob puede violar la segregación del atributo origin, permitiendo que se acceda desde una pestaña de navegación privada y que se pasen los datos entre la pestaña de navegación privada y una pestaña normal. Esto podría permitir la fuga de información privada específica del contexto de navegación privada. El problema se mitiga al requerir que el usuario introduzca la URL Blob manualmente para que no ocurra la violación de acceso. 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.
