Amazon Linux 2023 : sudo, sudo-devel, sudo-logsrvd (ALAS2023-2024-514)

high Nessus Plugin ID 190071

Language:

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-514 advisory.

 - 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. (CVE-2023-42465)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update sudo --releasever 2023.3.20240205' to update your system.
