Amazon Linux 2023 : sudo, sudo-devel, sudo-logsrvd (ALAS2023-2025-1070)

critical Nessus Plugin ID 241782

Language:

Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1070 advisory.

 Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host nor ALL, allows listed users to execute commands on unintended machines. (CVE-2025-32462)

 Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user- controlled directory is used with the --chroot option. (CVE-2025-32463)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update sudo --releasever 2023.8.20250707' to update your system.
