Descriptions

When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended.

Cuando curl versiones anteriores a 7.84.0, guarda datos de cookies, alt-svc y hsts en archivos locales, hace que la operación sea atómica al finalizar la operación con un renombramiento de un nombre temporal al nombre final del archivo de destino. En esa operación de renombramiento, podría accidentalmente *ampliar* los permisos del archivo de destino, dejando el archivo actualizado accesible a más usuarios de los previstos

A vulnerability was found in curl. This issue occurs because when curl saves cookies, alt-svc, and HSTS data to local files, it makes the operation atomic by finalizing the process with a rename from a temporary name to the final target file name. This flaw leads to unpreserved file permissions, either by mistake or by a malicious actor.
