NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3801-2.NASL description USN-3801-1 fixed vulnerabilities in Firefox. The update introduced various minor regressions. This update fixes the problems. We apologize for the inconvenience. Original advisory details : Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, bypass CSP restrictions, spoof the protocol registration notification bar, leak SameSite cookies, bypass mixed content warnings, or execute arbitrary code. (CVE-2018-12388, CVE-2018-12390, CVE-2018-12392, CVE-2018-12393, CVE-2018-12398, CVE-2018-12399, CVE-2018-12401, CVE-2018-12402, CVE-2018-12403) Multiple security issues were discovered with WebExtensions in Firefox. If a user were tricked in to installing a specially crafted extension, an attacker could potentially exploit these to bypass domain restrictions, gain additional privileges, or run content scripts in local pages without permission. (CVE-2018-12395, CVE-2018-12396, CVE-2018-12397). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 119146 published 2018-11-26 reporter Ubuntu Security Notice (C) 2018-2019 Canonical, Inc. / NASL script (C) 2018-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/119146 title Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 18.10 : firefox regressions (USN-3801-2) NASL family Windows NASL id MOZILLA_FIREFOX_63_0.NASL description The version of Mozilla Firefox installed on the remote Windows host is prior to 63. It is, therefore, affected by multiple vulnerabilities : - During HTTP Live Stream playback on Firefox for Android, audio data can be accessed across origins in violation of security policies. Because the problem is in the underlying Android service, this issue is addressed by treating all HLS streams as cross-origin and opaque to access. *Note: this issue only affects Firefox for Android. Desktop versions of Firefox are unaffected.* (CVE-2018-12391) - When manipulating user events in nested loops while opening a document through script, it is possible to trigger a potentially exploitable crash due to poor event handling. (CVE-2018-12392) - A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. *Note: 64-bit builds are not vulnerable to this issue.* (CVE-2018-12393) - By rewriting the Host request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. (CVE-2018-12395) - A vulnerability where a WebExtension can run content scripts in disallowed contexts following navigation or other events. This allows for potential privilege escalation by the WebExtension on sites where content scripts should not be run. (CVE-2018-12396) - A WebExtension can request access to local files without the warning prompt stating that the extension will last seen 2020-06-01 modified 2020-06-02 plugin id 118397 published 2018-10-25 reporter This script is Copyright (C) 2018-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/118397 title Mozilla Firefox < 63 Multiple Vulnerabilities NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3801-1.NASL description Multiple security issues were discovered in Firefox.
