Description

The watch implementation in the JavaScript engine in Mozilla Firefox before 46.0, Firefox ESR 38.x before 38.8, and Firefox ESR 45.x before 45.1 allows remote attackers to execute arbitrary code or cause a denial of service (generation-count overflow, out-of-bounds HashMap write access, and application crash) via a crafted web site.

Solution(s)

  • mozilla-firefox-esr-upgrade-38_8
  • mozilla-firefox-esr-upgrade-45_1
  • mozilla-firefox-upgrade-46_0
