The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4241-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, conduct cross-site scripting (XSS) attacks, or execute arbitrary code. (CVE-2019-17005,     CVE-2019-17008, CVE-2019-17010, CVE-2019-17011, CVE-2019-17012, CVE-2019-17016, CVE-2019-17017,     CVE-2019-17022, CVE-2019-17024, CVE-2019-17026)

    It was discovered that NSS incorrectly handled certain memory operations. A remote attacker could     potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2019-11745)

The version of thunderbird installed on the remote host is prior to 68.4.1-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1393 advisory.

    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. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. (CVE-2019-17016)

    Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.4 and Firefox <     72.(CVE-2019-17024)

    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's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability. Two     WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox ESR     < 68.4 and Firefox < 72.(CVE-2019-17022)

    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. This     vulnerability affects Firefox ESR < 68.4 and Firefox < 72. (CVE-2019-17017)

    Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type     confusion. We are aware of targeted attacks in the wild abusing this flaw.(CVE-2019-17026)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4234-1 advisory.

    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, obtain     sensitive information, bypass Content Security Policy (CSP) restrictions, conduct cross-site scripting     (XSS) attacks, or execute arbitrary code.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An issue was found in the IonMonkey JIT compiler of the Mozilla Firefox web browser which could lead to arbitrary code execution.

For Debian 8 'Jessie', this problem has been fixed in version 68.4.1esr-1~deb8u1.

We recommend that you upgrade your firefox-esr packages.

According to the versions of the mozjs60 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - 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. This     vulnerability affects Firefox ESR < 68.4 and Firefox < 72. (CVE-2019-17017)

  - Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type     confusion. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects     Firefox ESR < 68.4.1, Thunderbird < 68.4.1, and Firefox < 72.0.1. (CVE-2019-17026)

  - The type inference system allows the compilation of functions that can cause type confusions between     arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor     function is entered through on-stack replacement (OSR). This allows for possible arbitrary reading and     writing of objects during an exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR     < 60.6, and Firefox < 66. (CVE-2019-9791)

  - A vulnerability where type-confusion in the IonMonkey just-in-time (JIT) compiler could potentially be     used by malicious JavaScript to trigger a potentially exploitable crash. This vulnerability affects     Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. (CVE-2019-9795)

  - Incorrect alias information in IonMonkey JIT compiler for Array.prototype.slice method may lead to missing     bounds check and a buffer overflow. This vulnerability affects Firefox < 66.0.1, Firefox ESR < 60.6.1, and     Thunderbird < 60.6.1. (CVE-2019-9810)

  - Incorrect handling of __proto__ mutations may lead to type confusion in IonMonkey JIT code and can be     leveraged for arbitrary memory read and write. This vulnerability affects Firefox < 66.0.1, Firefox ESR <     60.6.1, and Thunderbird < 60.6.1. (CVE-2019-9813)
