CVE-2023-42465 Open this link in a new tabHow to fix?
Upgrade Centos:8 sudo to version 0:1.9.5p2-1.el8_9 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream sudo package and not the sudo package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
Sudo before 1.9.15 might allow row hammer attacks (for authentication bypass or privilege escalation) because application logic sometimes is based on not equaling an error value (instead of equaling a success value), and because the values do not resist flips of a single bit.
