Descriptions

An issue was discovered in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. Due to the way rename() across filesystems is implemented, it is possible that file being renamed is briefly available with wrong permissions while the rename is ongoing, thus enabling unauthorized users to access the data.

Se ha detectado un fallo en PHP en versiones anteriores a la 7.1.27, en las 7.2.x anteriores a la 7.2.16 y en las 7.3.x anteriores a la 7.3.3. Debido a la manera en la que "rename()" se implementa en los sistemas de archivos es posible que el archivo que se está renombrado esté brevemente disponible con los permisos incorrectos mientras que dicho proceso siga en curso, habilitando el acceso a los datos a usuarios no autenticados.
