CVE-2023-42465 Open this link in a new tabHow to fix?
There is no fixed version for Debian:11 sudo.
NVD Description
Note: Versions mentioned in the description apply only to the upstream sudo package and not the sudo package as distributed by Debian.
See How to fix? for Debian:11 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.
