Multiple security vulnerabilities were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to conduct cross-site scripting attacks, obtain sensitive information, cause a denial of service via application crash, or execute arbitrary code.
