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, read uninitialized memory, bypass same-origin restrictions, bypass CORS restrictions, bypass CSRF protections, obtain sensitive information, or execute arbitrary code.
