CVE-2019-20044 – zsh: insecure dropping of privileges when unsetting PRIVILEGED option
https://notcve.org/view.php?id=CVE-2019-20044
In Zsh before 5.8, attackers able to execute commands can regain privileges dropped by the --no-PRIVILEGED option. Zsh fails to overwrite the saved uid, so the original privileges can be restored by executing MODULE_PATH=/dir/with/module zmodload with a module that calls setuid(). En Zsh versiones anteriores a 5.8, los atacantes capaces de ejecutar comandos pueden recuperar privilegios eliminados mediante la opción --no-PRIVILEGED. Zsh presenta un fallo al sobrescribir el uid guardado, ya que los privilegios originales pueden ser restaurados mediante una ejecución de zmodload de MODULE_PATH=/dir/with/module con un módulo que llama a la función setuid(). A flaw was found in zsh. • http://seclists.org/fulldisclosure/2020/May/49 http://seclists.org/fulldisclosure/2020/May/53 http://seclists.org/fulldisclosure/2020/May/55 http://seclists.org/fulldisclosure/2020/May/59 http://zsh.sourceforge.net/releases.html https://github.com/XMB5/zsh-privileged-upgrade https://lists.debian.org/debian-lts-announce/2020/03/msg00004.html https://lists.debian.org/debian-lts-announce/2020/12/msg00000.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproje • CWE-271: Privilege Dropping / Lowering Errors CWE-273: Improper Check for Dropped Privileges •

https://notcve.org/view.php?id=CVE-2019-15126
An issue was discovered on Broadcom Wi-Fi client devices. Specifically timed and handcrafted traffic can cause internal errors (related to state transitions) in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure over the air for a discrete set of traffic, a different vulnerability than CVE-2019-9500, CVE-2019-9501, CVE-2019-9502, and CVE-2019-9503. Se detectó un problema en los dispositivos cliente de Broadcom Wi-Fi. Específicamente un tráfico diseñado minuciosamente y sincronizado puede causar errores internos (relacionados con las transiciones de estado) en un dispositivo WLAN que conllevan a un cifrado de Wi-Fi de Capa 2 inapropiado con una consiguiente posibilidad de divulgación de información por medio del aire para un conjunto de tráfico discreto, una vulnerabilidad diferente de CVE-2019-9500, CVE-2019-9501, CVE-2019-9502 y CVE-2019-9503. • https://www.exploit-db.com/exploits/48233 http://packetstormsecurity.com/files/156809/Broadcom-Wi-Fi-KR00K-Proof-Of-Concept.html http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2020-003.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200527-01-wifi-en http://www.huawei.com/en/psirt/security-notices/huawei-sn-20200228-01-kr00k-en https://cert-portal.siemens.com/productcert/pdf/ssa-712518.pdf https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2020-0001 https: • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
