NASL family MacOS X Local Security Checks NASL id MACOS_FIREFOX_72_0.NASL description The version of Firefox installed on the remote macOS or Mac OS X host is prior to 72.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-01 advisory, including the following: - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in data exfiltration. (CVE-2019-17016) - Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. (CVE-2019-17017) - If an XML file is served with a Content Security Policy and the XML file includes an XSL stylesheet, the Content Security Policy will not be applied to the contents of the XSL stylesheet. If the XSL sheet e.g. includes JavaScript, it would bypass any of the restrictions of the Content Security Policy applied to the XML document. (CVE-2019-17020) - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage; however, if a webpage subsequently copies the node last seen 2020-06-01 modified 2020-06-02 plugin id 132708 published 2020-01-08 reporter This script is Copyright (C) 2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/132708 title Mozilla Firefox < 72.0 Multiple Vulnerabilities code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Mozilla Foundation Security Advisory mfsa2020-01. # The text itself is copyright (C) Mozilla Foundation. include('compat.inc'); if (description) { script_id(132708); script_version("1.5"); script_cvs_date("Date: 2020/02/14"); script_cve_id( "CVE-2019-17016", "CVE-2019-17017", "CVE-2019-17020", "CVE-2019-17022", "CVE-2019-17023", "CVE-2019-17024", "CVE-2019-17025" ); script_xref(name:"MFSA", value:"2020-01"); script_name(english:"Mozilla Firefox < 72.0 Multiple Vulnerabilities"); script_set_attribute(attribute:"synopsis", value: "A web browser installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities."); script_set_attribute(attribute:"description", value: "The version of Firefox installed on the remote macOS or Mac OS X host is prior to 72.0.

If the client gets into this state, incoming Application Data records will be ignored.

It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-01 advisory, including the following: - During the initialization of a new content process, a pointer offset can be manipulated leading to memory corruption and a potentially exploitable crash in the parent process. (CVE-2019-17015) - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly rewrites a @namespace rule.

(CVE-2019-17017) - When in Private Browsing Mode on Windows 10, the Windows keyboard may retain word suggestions to improve the accuracy of the keyboard.
