AlmaLinux 9.2 [TuxCare] Security Update: cloud-init Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2025:1760018787)

medium Nessus Plugin ID 351631

Language:

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2025:1760018787 advisory.

 - cloud-init through 25.1.2 includes the systemd socket unit cloud-init-hotplugd.socket with default SocketMode that grants 0666 permissions, making it world-writable. This is used for the /run/cloud- init/hook-hotplug-cmd FIFO. An unprivileged user could trigger hotplug-hook commands. (CVE-2024-11584)

 - When a non-x86 platform is detected, cloud-init grants root access to a hardcoded url with a local IP address. To prevent this, cloud-init default configurations disable platform enumeration. (CVE-2024-6174)

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

Solution

Update the affected cloud-init package based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2025:1760018787.
