Description

The maintenance service in Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 on Windows does not prevent MAR extracted-file modification during updater execution, which might allow local users to gain privileges via a Trojan horse file.

Solution(s)

  • mozilla-firefox-esr-upgrade-45_2
  • mozilla-firefox-upgrade-47_0
