Cure53 DOMPurify before 2.0.17 allows mutation XSS. This occurs because a serialize-parse roundtrip does not necessarily return the original DOM tree, and a namespace can change from HTML to MathML, as demonstrated by nesting of FORM elements. Cure53 DOMPurify versiones anteriores a 2.0.17, permite una mutación de XSS. Esto ocurre porque un viaje de ida y vuelta de análisis serializado no necesariamente devuelve el árbol DOM original, y un espacio de nombres puede cambiar de HTML a MathML, como es demostrado al anidar los elementos FORM • https://github.com/cure53/DOMPurify/commit/02724b8eb048dd219d6725b05c3000936f11d62d https://github.com/cure53/DOMPurify/compare/2.0.16...2.0.17 https://lists.debian.org/debian-lts-announce/2020/10/msg00029.html https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-26870 https://research.securitum.com/mutation-xss-via-mathml-mutation-dompurify-2-0-17-bypass https://www.oracle.com//security-alerts/cpujul2021.html • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 6.5EPSS: 1%CPEs: 21EXPL: 0CVE-2020-8927 – Buffer overflow in Brotli library
https://notcve.org/view.php?id=CVE-2020-8927
A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a "one-shot" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits. Se presenta un desbordamiento del búfer en la biblioteca Brotli versiones anteriores a 1.0.8, donde un atacante que controla la longitud de entrada de una petición de descompresión "one-shot" en un script puede desencadenar un bloqueo, que ocurre cuando se copian fragmentos de datos de más de 2 GiB . Se recomienda actualizar su biblioteca de Brotli a la versión 1.0.8 o posterior. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00108.html https://github.com/google/brotli/releases/tag/v1.0.9 https://lists.debian.org/debian-lts-announce/2020/12/msg00003.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/356JOYTWW4BWSZ42SEFLV7NYHL3S3AEH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4TOGTZ2ZWDH662ZNFFSZVL3M5AJXV6JF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-130: Improper Handling of Length Parameter Inconsistency •

https://notcve.org/view.php?id=CVE-2020-16856
<p>A remote code execution vulnerability exists in Visual Studio when it improperly handles objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-16856 •
