https://notcve.org/view.php?id=CVE-2019-17023
After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data records will be ignored. This vulnerability affects Firefox < 72. Después de que HelloRetryRequest haya sido enviado, el cliente puede negociar un protocolo inferior que TLS versión 1.3, resultando en una transición de estado no válida en TLS State Machine. Si el cliente entra en este estado, los registros de Datos de Aplicación entrantes serian ignorados. • https://bugzilla.mozilla.org/show_bug.cgi?id=1590001 https://usn.ubuntu.com/4234-1 https://usn.ubuntu.com/4397-1 https://www.debian.org/security/2020/dsa-4726 https://www.mozilla.org/security/advisories/mfsa2020-01 https://access.redhat.com/security/cve/CVE-2019-17023 https://bugzilla.redhat.com/show_bug.cgi?id=1791225 • CWE-287: Improper Authentication •
CVSS: 6.1EPSS: 0%CPEs: 17EXPL: 0CVE-2019-17022 – Mozilla: CSS sanitization does not escape HTML tags
https://notcve.org/view.php?id=CVE-2019-17022
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. Al pegar un <style> etiqueta del portapapeles en un editor de texto enriquecido, el saneador CSS no escapa caracteres < y >. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00043.html http://packetstormsecurity.com/files/155912/Slackware-Security-Advisory-mozilla-thunderbird-Updates.html https://access.redhat.com/errata/RHSA-2020:0085 https://access.redhat.com/errata/RHSA-2020:0086 https://access.redhat.com/errata/RHSA-2020:0111 https://access.redhat.com/errata/RHSA-2020:0120 https://access.redhat.com/errata/RHSA-2020:0123 https: • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

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. This vulnerability affects Firefox < 72. Si un archivo XML es servido con la Política de Seguridad de Contenido y el archivo XML incluye una hoja de estilo XSL, la Política de Seguridad de Contenido no será aplicada al contenido de la hoja de estilo XSL. Si la hoja XSL, por ejemplo, incluye JavaScript, omitiría cualquiera de las restricciones de la Política de Seguridad de Contenido aplicada al documento XML. • https://bugzilla.mozilla.org/show_bug.cgi?id=1597645 https://usn.ubuntu.com/4234-1 https://www.mozilla.org/security/advisories/mfsa2020-01 • CWE-611: Improper Restriction of XML External Entity Reference •

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. Debido a una falta de tipos de objetos del manejo de casos, podría ocurrir una vulnerabilidad de confusión de tipos, resultando en un bloqueo.

CVSS: 6.1EPSS: 0%CPEs: 17EXPL: 0CVE-2019-17016 – Mozilla: Bypass of @namespace CSS sanitization during pasting
https://notcve.org/view.php?id=CVE-2019-17016
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. Al pegar un <style> etiqueta del portapapeles en un editor de texto enriquecido, el saneador CSS reescribe incorrectamente una regla @namespace. Esto podría permitir una inyección en ciertos tipos de sitios web resultando en la filtración de datos. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00043.html http://packetstormsecurity.com/files/155912/Slackware-Security-Advisory-mozilla-thunderbird-Updates.html https://access.redhat.com/errata/RHSA-2020:0085 https://access.redhat.com/errata/RHSA-2020:0086 https://access.redhat.com/errata/RHSA-2020:0111 https://access.redhat.com/errata/RHSA-2020:0120 https://access.redhat.com/errata/RHSA-2020:0123 https: • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
