Descriptions

postgresql before versions 10.4, 9.6.9 is vulnerable in the adminpack extension, the pg_catalog.pg_logfile_rotate() function doesn't follow the same ACLs than pg_rorate_logfile. If the adminpack is added to a database, an attacker able to connect to it could exploit this to force log rotation.

postgresql en versiones anteriores a la 10.4 y la 9.6.9 es vulnerable en la extensión adminpack. La función pg_catalog.pg_logfile_rotate() no sigue las mismas lista de control de acceso que pg_rorate_logfile. Si adminpack se añade a una base de datos, un atacante que sea capaz de conectarse a ella podría explotar esta rotación forzada de registro.

It was found that pg_catalog.pg_logfile_rotate(), from the adminpack extension, did not follow the same ACLs than pg_rorate_logfile. If the adminpack is added to a database, an attacker able to connect to it could use this flaw to force log rotation.

An update that solves 7 vulnerabilities and has two fixes is now available. This update for postgresql96, postgresql10 and postgresql12 fixes the following issues. Postgresql10 was updated to 10.13.
