Descriptions
The Debian pg_ctlcluster, pg_createcluster, and pg_upgradecluster scripts, as distributed in the Debian postgresql-common package before 181+deb9u1 for PostgreSQL (and other packages related to Debian and Ubuntu), handled symbolic links insecurely, which could result in local denial of service by overwriting arbitrary files.
Los scripts de Debian pg_ctlcluster, pg_createcluster y pg_upgradecluster, tal y como se distribuyen en el paquete de Debian postgresql-common anterior a 181+deb9u1 para PostgreSQL (y otros paquetes relacionados con Debian y Ubuntu), manipularon vínculos simbólicos de forma no segura, lo que podría desembocar en una denegación de servicio local sobrescribiendo archivos arbitrarios.
