script_tag(name:"insight", value:"* CVE-2019-10208: `TYPE` in `pg_temp` executes arbitrary SQL during `SECURITY DEFINER` execution
Versions Affected: 9.4 - 11
Given a suitable `SECURITY DEFINER` function, an attacker can execute arbitrary SQL under the identity of the function owner. An attack requires `EXECUTE` permission on the function, which must itself contain a function call having inexact argument type match. For example, `length('foo'::varchar)` and `length('foo')` are inexact, while `length('foo'::text)` is exact. As part of exploiting this vulnerability, the attacker uses `CREATE DOMAIN` to create a type in a `pg_temp` schema. The attack pattern and fix are similar to that for CVE-2007-2138.
Writing `SECURITY DEFINER` functions continues to require following the considerations noted in the documentation:

The PostgreSQL project thanks Tom Lane for reporting this problem.
For Debian 8 Jessie, this problem has been fixed in version 9.4.24-0+deb8u1.
We recommend that you upgrade your postgresql-9.4 packages.
Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
