PostgreSQL versions before 9.2.22, 9.3.18, 9.4.13, 9.5.8 and 9.6.4 are vulnerable to authorization flaw allowing remote authenticated attackers to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so. PostgreSQL en sus versiones anteriores a 9.2.22, 9.3.18, 9.4.13, 9.5.8 y 9.6.4 es vulnerable a un fallo de autorización que permite que los atacantes remotos autenticados recuperen contraseñas de los mapeos de usuarios definidos por los propietarios del servidor extranjero sin tener privilegios para ello. An authorization flaw was found in the way PostgreSQL handled access to the pg_user_mappings view on foreign servers. A remote, authenticated attacker could potentially use this flaw to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so. • http://www.debian.org/security/2017/dsa-3935 http://www.debian.org/security/2017/dsa-3936 http://www.securityfocus.com/bid/100275 http://www.securitytracker.com/id/1039142 https://access.redhat.com/errata/RHSA-2017:2677 https://access.redhat.com/errata/RHSA-2017:2678 https://access.redhat.com/errata/RHSA-2017:2728 https://security.gentoo.org/glsa/201710-06 https://www.postgresql.org/about/news/1772 https://access.redhat.com/security/cve/CVE-2017-7547 https:// • CWE-522: Insufficiently Protected Credentials •

PostgreSQL versions before 9.4.13, 9.5.8 and 9.6.4 are vulnerable to authorization flaw allowing remote authenticated attackers with no privileges on a large object to overwrite the entire contents of the object, resulting in a denial of service. PostgreSQL en sus versiones anteriores a 9.4.13, 9.5.8 y 9.6.4 es vulnerable a un fallo de autorización que permite que atacantes remotos sin privilegios sobre un gran objeto sobreescriban todo el contenido del objeto. Esto resultaría en una denegación de servicio. An authorization flaw was found in the way PostgreSQL handled large objects. A remote, authenticated attacker with no privileges on a large object could potentially use this flaw to overwrite the entire content of the object, thus resulting in denial of service. • http://www.debian.org/security/2017/dsa-3935 http://www.debian.org/security/2017/dsa-3936 http://www.securityfocus.com/bid/100276 http://www.securitytracker.com/id/1039142 https://access.redhat.com/errata/RHSA-2017:2677 https://access.redhat.com/errata/RHSA-2017:2678 https://security.gentoo.org/glsa/201710-06 https://www.postgresql.org/about/news/1772 https://access.redhat.com/security/cve/CVE-2017-7548 https://bugzilla.redhat.com/show_bug.cgi?id=1477187 • CWE-862: Missing Authorization •

PostgreSQL versions before 9.2.22, 9.3.18, 9.4.13, 9.5.8 and 9.6.4 are vulnerable to incorrect authentication flaw allowing remote attackers to gain access to database accounts with an empty password. PostgreSQL en sus versiones anteriores a 9.2.22, 9.3.18, 9.4.13, 9.5.8 y 9.6.4 es vulnerable a un fallo de autenticación incorrecta que permite que atacantes remotos obtengan acceso a cuentas de la base de datos con una contraseña vacía. It was found that authenticating to a PostgreSQL database account with an empty password was possible despite libpq's refusal to send an empty password. A remote attacker could potentially use this flaw to gain access to database accounts with empty passwords. • http://www.debian.org/security/2017/dsa-3935 http://www.debian.org/security/2017/dsa-3936 http://www.securityfocus.com/bid/100278 http://www.securitytracker.com/id/1039142 https://access.redhat.com/errata/RHSA-2017:2677 https://access.redhat.com/errata/RHSA-2017:2678 https://access.redhat.com/errata/RHSA-2017:2728 https://access.redhat.com/errata/RHSA-2017:2860 https://security.gentoo.org/glsa/201710-06 https://www.postgresql.org/about/news/1772 https://access • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2017-7485
In PostgreSQL 9.3.x before 9.3.17, 9.4.x before 9.4.12, 9.5.x before 9.5.7, and 9.6.x before 9.6.3, it was found that the PGREQUIRESSL environment variable was 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. En PostgreSQL, en versiones 9.3.x anteriores a la 9.3.17, versiones 9.4.x anteriores a la 9.4.12, versiones 9.5.x anteriores a la 9.5.7, y versiones 9.6.x anteriores a la 9.6.3, se ha descubierto que la variable de entorno PGREQUIRESSL ya no requería una conexión SSL/TLS a un servidor PostgreSQL. Un atacante Man-in-the-Middle (MitM) activo podría utilizar este fallo para eliminar la protección SSL/TLS de una conexión entre un cliente y un servidor. It was discovered that the PostgreSQL client library (libpq) did not enforce the use of TLS/SSL for a connection to a PostgreSQL server when the PGREQUIRESSL environment variable was set. • http://www.debian.org/security/2017/dsa-3851 http://www.securityfocus.com/bid/98461 http://www.securitytracker.com/id/1038476 https://access.redhat.com/errata/RHSA-2017:1677 https://access.redhat.com/errata/RHSA-2017:1678 https://access.redhat.com/errata/RHSA-2017:1838 https://access.redhat.com/errata/RHSA-2017:2425 https://security.gentoo.org/glsa/201710-06 https://www.postgresql.org/about/news/1746 https://access.redhat.com/security/cve/CVE-2017-7485 https:/ • CWE-311: Missing Encryption of Sensitive Data CWE-390: Detection of Error Condition Without Action •
