"value": "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."

"value": "calamares-nixos-extensions proporciona la marca Calamares y m\u00f3dulos para NixOS, una distribuci\u00f3n de GNU/Linux. Usuarios que instalaron NixOS a trav\u00e9s del instalador gr\u00e1fico que utilizaron la partici\u00f3n manual del disco para crear una configuraci\u00f3n en la que el sistema se inici\u00f3 a trav\u00e9s de BIOS heredado en lugar de UEFI; algunas particiones del disco est\u00e1n cifradas; pero las particiones que contienen `/` o `/boot` no est\u00e1n 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 configuraci\u00f3n de partici\u00f3n autom\u00e1tica predeterminada en los sistemas BIOS heredados. El problema se solucion\u00f3 en calamares-nixos-extensions 0.3.17, que se incluy\u00f3 en NixOS. Las im\u00e1genes del instalador actual para los canales NixOS 24.05 e inestable (24.11) no se ven afectadas. La correcci\u00f3n lleg\u00f3 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 im\u00e1genes del instalador descargadas antes de esas fechas pueden ser vulnerables. La mejor soluci\u00f3n para los usuarios afectados probablemente sea hacer una copia de seguridad de sus datos y realizar una reinstalaci\u00f3n completa. Sin embargo, el procedimiento de mitigaci\u00f3n en GHSA-3rvf-24q2-24ww deber\u00eda funcionar \u00fanicamente en el caso en el que `/` est\u00e9 cifrado pero `/boot` no. Si `/` no est\u00e1 cifrado, entonces ser\u00e1 necesario eliminar el archivo `/crypto_keyfile.bin` adem\u00e1s de seguir los pasos de correcci\u00f3n del aviso anterior. Este problema es una regresi\u00f3n parcial de CVE-2023-36476/GHSA-3rvf-24q2-24ww, que era m\u00e1s grave al aplicarse a la configuraci\u00f3n predeterminada en los sistemas BIOS."
