NASL family MacOS X Local Security Checks NASL id MACOSX_FIREFOX_45.NASL description The version of Firefox installed on the remote Mac OS X host is prior to 45. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these issues by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user. last seen 2020-06-01 modified 2020-06-02 plugin id 89873 published 2016-03-11 reporter This script is Copyright (C) 2016-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/89873 title Firefox < 45 Multiple Vulnerabilities (Mac OS X) code # # (C) Tenable Network Security, Inc. # include("compat.inc"); if (description) { script_id(89873); script_version("1.11"); script_cvs_date("Date: 2019/11/20"); script_cve_id( "CVE-2016-1950", "CVE-2016-1952", "CVE-2016-1953", "CVE-2016-1954", "CVE-2016-1955", "CVE-2016-1956", "CVE-2016-1957", "CVE-2016-1958", "CVE-2016-1959", "CVE-2016-1960", "CVE-2016-1961", "CVE-2016-1962", "CVE-2016-1963", "CVE-2016-1964", "CVE-2016-1965", "CVE-2016-1966", "CVE-2016-1967", "CVE-2016-1968", "CVE-2016-1969", "CVE-2016-1970", "CVE-2016-1971", "CVE-2016-1972", "CVE-2016-1973", "CVE-2016-1974", "CVE-2016-1975", "CVE-2016-1976", "CVE-2016-1977", "CVE-2016-1979", "CVE-2016-2790", "CVE-2016-2791", "CVE-2016-2792", "CVE-2016-2793", "CVE-2016-2794", "CVE-2016-2795", "CVE-2016-2796", "CVE-2016-2797", "CVE-2016-2798", "CVE-2016-2799", "CVE-2016-2800", "CVE-2016-2801", "CVE-2016-2802" ); script_xref(name:"MFSA", value:"2016-16"); script_xref(name:"MFSA", value:"2016-17"); script_xref(name:"MFSA", value:"2016-18"); script_xref(name:"MFSA", value:"2016-19"); script_xref(name:"MFSA", value:"2016-20"); script_xref(name:"MFSA", value:"2016-21"); script_xref(name:"MFSA", value:"2016-22"); script_xref(name:"MFSA", value:"2016-23"); script_xref(name:"MFSA", value:"2016-24"); script_xref(name:"MFSA", value:"2016-25"); script_xref(name:"MFSA", value:"2016-26"); script_xref(name:"MFSA", value:"2016-27"); script_xref(name:"MFSA", value:"2016-28"); script_xref(name:"MFSA", value:"2016-29"); script_xref(name:"MFSA", value:"2016-30"); script_xref(name:"MFSA", value:"2016-31"); script_xref(name:"MFSA", value:"2016-32"); script_xref(name:"MFSA", value:"2016-33"); script_xref(name:"MFSA", value:"2016-34"); script_xref(name:"MFSA", value:"2016-35"); script_xref(name:"MFSA", value:"2016-36"); script_xref(name:"MFSA", value:"2016-37"); script_xref(name:"MFSA", value:"2016-38"); script_name(english:"Firefox < 45 Multiple Vulnerabilities (Mac OS X)"); script_summary(english:"Checks the version of Firefox."); script_set_attribute(attribute:"synopsis", value: "The remote Mac OS X host contains a web browser that is affected by multiple vulnerabilities."); script_set_attribute(attribute:"description", value: "The version of Firefox installed on the remote Mac OS X host is prior to 45.
