Original advisory details:
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 read uninitialized memory, obtain sensitive
information, bypass phishing and malware protection, spoof the origin in
modal dialogs, conduct cross-site scripting (XSS) attacks, cause a denial
of service via application crash, or execute arbitrary code.
