CVE-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') •

CVE-2019-17017 – Mozilla: Type Confusion in XPCVariant.cpp
https://notcve.org/view.php?id=CVE-2019-17017
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.

CVE-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') •

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.*. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. Durante la inicialización de un nuevo proceso de contenido, un desplazamiento del puntero puede ser manipulado lo que conlleva a una corrupción de memoria y un bloqueo explotable potencialmente en el proceso principal. * Nota: este problema solo ocurre en Windows. • 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://bugzilla.mozilla.org/show_bug.cgi?id=1599005 https://seclists.org/bugtraq/2020/Jan/18 https://www.mozilla.org/security/advisories/mfsa2020-01 https://www.mozilla.org/security/advisories/mfsa2020-02 • CWE-787: Out-of-bounds Write •
