Diagnostics Hub Standard Collector Elevation of Privilege Vulnerability Una vulnerabilidad de Elevación de Privilegios en Diagnostics Hub Standard Collector This vulnerability allows local attackers to escalate privileges on affected installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Microsoft Diagnostics Hub Standard Collector Service. By creating a symbolic link, an attacker can abuse the service to delete a directory. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-42277 https://www.zerodayinitiative.com/advisories/ZDI-21-1306 • CWE-269: Improper Privilege Management •

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 •
