CVE-2024-43378

Estado: AplazadaAlta (7.8)—

calamares-nixos-extensions provides Calamares branding and modules for NixOS, a distribution of GNU/Linux. Users who installed NixOS through the graphical installer who used manual disk partitioning to create a setup where the system was booted via legacy BIOS rather than UEFI; some disk partitions are encrypted; but the partitions containing either `/` or `/boot` are unencrypted; have their LUKS disk encryption key file in plain text either in `/crypto_keyfile.bin`, or in a CPIO archive attached to their NixOS initrd. `nixos-install` is not affected, nor are UEFI installations, nor was the default automatic partitioning configuration on legacy BIOS systems. The problem has been fixed in calamares-nixos-extensions 0.3.17, which was included in NixOS. The current installer images for the NixOS 24.05 and unstable (24.11) channels are unaffected. The fix reached 24.05 at 2024-08-13 20:06:59 UTC, and unstable at 2024-08-15 09:00:20 UTC. Installer images downloaded before those times may be vulnerable. The best solution for affected users is probably to back up their data and do a complete reinstallation. However, the mitigation procedure in GHSA-3rvf-24q2-24ww should work solely for the case where `/` is encrypted but `/boot` is not. If `/` is unencrypted, then the `/crypto_keyfile.bin` file will need to be deleted in addition to the remediation steps in the previous advisory. This issue is a partial regression of CVE-2023-36476 / GHSA-3rvf-24q2-24ww, which was more severe as it applied to the default configuration on BIOS systems.

Usuarios que instalaron NixOS a través del instalador gráfico que utilizaron la partición manual del disco para crear una configuración en la que el sistema se inició a través de BIOS heredado en lugar de UEFI; algunas particiones del disco están cifradas; pero las particiones que contienen `/` o `/boot` no están cifradas; tener su archivo de clave de cifrado de disco LUKS en texto plano, ya sea en `/crypto_keyfile.bin` o en un archivo CPIO adjunto a su initrd de NixOS. `nixos-install` no se ve afectado, ni tampoco las instalaciones UEFI, ni la configuración de partición automática predeterminada en los sistemas BIOS heredados. El problema se solucionó en calamares-nixos-extensions 0.3.17, que se incluyó en NixOS. Las imágenes del instalador actual para los canales NixOS 24.05 e inestable (24.11) no se ven afectadas. La corrección llegó a las 24.05 el 13 de agosto de 2024 a las 20:06:59 UTC y fue inestable el 15 de agosto de 2024 a las 09:00:20 UTC. Las imágenes del instalador descargadas antes de esas fechas pueden ser vulnerables. La mejor solución para los usuarios afectados probablemente sea hacer una copia de seguridad de sus datos y realizar una reinstalación completa. Sin embargo, el procedimiento de mitigación en GHSA-3rvf-24q2-24ww debería funcionar únicamente en el caso en el que `/` esté cifrado pero `/boot` no. Si `/` no está cifrado, entonces será necesario eliminar el archivo `/crypto_keyfile.bin` además de seguir los pasos de corrección del aviso anterior. Este problema es una regresión parcial de CVE-2023-36476/GHSA-3rvf-24q2-24ww, que era más grave al aplicarse a la configuración predeterminada en los sistemas BIOS."
