Description Arvid Requate univentionstaff 2017-05-23 19:06:44 CEST
Upstream Debian package version 9.1.20-0+deb7u1 fixes these issues:

* Some selectivity estimation functions in PostgreSQL do not check user privileges before providing information from pg_statistic, possibly leaking information. An unprivileged attacker could use this flaw to steal some information from tables they are otherwise not allowed to access. (CVE-2017-7484)

* The PGREQUIRESSL environment variable is no longer enforcing a SSL/TLS connection to a PostgreSQL server. An active Man-in-the-Middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client and a server. (CVE-2017-7485)

* Information leak in pg_user_mappings view which discloses foreign server passwords to any user having USAGE privilege on the associated foreign server. (CVE-2017-7486)
