  1. A new security flaw has been identified in the sudo software. Sudo, which is installed by default in many operating systems, is by default setuid root. This means that any shortcomings can lead to local users being able to obtain root permissions. Over the years, sudo has also become larger and more features have been added. This has i.a. led to OpenBSD now having an option called doas. Yesterday, the American security company Qualys reported that they had identified a vulnerability in sudo (CVE-2021-3156).
