Security readout for executives and security teams
CVE-2016-1958 is an address bar spoofing flaw in older Mozilla Firefox releases. A remote attacker could use a javascript: URL to make the browser show misleading location information, supporting phishing or trust deception. Sources identify fixes in Firefox 45.0 and Firefox ESR 38.7. Exposure is mainly legacy endpoints, kiosk systems, or managed Linux desktops still running Firefox before 45.0 or ESR 38.x before 38.7. Modern supported Firefox installations should not be exposed if vendor browser packages are current. Treat as a legacy-browser hygiene issue with phishing risk. Prioritize remediation where old Firefox builds remain on user-facing desktops, shared systems, or unmanaged Linux endpoints. Mitigation focus: Upgrade Firefox to 45.0 or later, or Firefox ESR to 38.7 or later.; Apply relevant OS vendor browser updates from Mozilla, Ubuntu, Debian, SUSE, or Gentoo guidance.; Remove unsupported Firefox ESR 38.x builds from managed endpoint baselines..
