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 •
