The remote Oracle Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2020-0086 advisory.

    - Added fix for mozbz#1348168/CVE-2017-5428

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

The remote CentOS Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:0123 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)

  - 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)

  - 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)

  - 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)

  - 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)

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

Multiple security issues have been found in Thunderbird which could potentially result in the execution of arbitrary code or information disclosure.

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.

  - Mozilla developers Karl Tomlinson, Jason Kratzer, Tyson Smith, Jon Coppeard, and Christian Holler reported     memory safety bugs present in Firefox 71. 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.
    (CVE-2019-17025)

  - 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.  Note: this issue only occurs on     Windows. Other operating systems are unaffected. (CVE-2019-17015)

  - When pasting a <code><style></code> 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)

  - When in Private Browsing Mode on Windows 10, the Windows keyboard may retain word suggestions to improve     the accuracy of the keyboard. (CVE-2019-17018)

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

This update upgrades Firefox to version 68.4.1 ESR.

Security Fix(es) :

  - Mozilla: IonMonkey type confusion with StoreElementHole     and FallibleStoreElement (CVE-2019-17026)

  - Mozilla: Bypass of @namespace CSS sanitization during     pasting (CVE-2019-17016)

  - Mozilla: Type Confusion in XPCVariant.cpp     (CVE-2019-17017)

  - Mozilla: Memory safety bugs fixed in Firefox 72 and     Firefox ESR 68.4 (CVE-2019-17024)

  - Mozilla: CSS sanitization does not escape HTML tags     (CVE-2019-17022)

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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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