Several vulnerabilities were discovered in PostgreSQL, an object-relational SQL database. An attacker could have an opportunity to complete a MITM attack, execute arbitrary SQL functions under the identity of a superuser, execute arbitrary code as the operating system account running psql when connecting to a rogue server, and corrupt server memory, in some conditions.

For Debian 8 jessie, these problems have been fixed in version 9.4.26-0+deb8u4.

We recommend that you upgrade your postgresql-9.4 packages.
