Summary
When etcupdate encounters conflicts while merging files, it saves a version containing conflict markers in /var/db/etcupdate/conflicts. This version does not preserve the mode of the input file, and is world-readable. This applies to files that would normally have restricted visibility, such as /etc/master.passwd.
An unprivileged local user may be able to read encrypted root and user passwords from the temporary master.passwd file created in /var/db/etcupdate/conflicts. This is possible only when conflicts within the password file arise during an update, and the unprotected file is deleted when conflicts are resolved.

"value": "Cuando etcupdate encuentra conflictos al fusionar archivos, guarda una versi\u00f3n que contiene marcadores de conflicto en /var/db/etcupdate/conflicts. Esta versi\u00f3n no conserva el modo del archivo de entrada y es legible por todo el mundo. Esto se aplica a archivos que normalmente tendr\u00edan visibilidad restringida, como /etc/master.passwd. Un usuario local sin privilegios puede leer contrase\u00f1as de usuario y ra\u00edz cifradas desde el archivo temporal master.passwd manipulado en /var/db/etcupdate/conflicts. Esto es posible solo cuando surgen conflictos dentro del archivo de contrase\u00f1as durante una actualizaci\u00f3n y el archivo desprotegido se elimina cuando se resuelven los conflictos."
