USN-4472-1: PostgreSQL vulnerabilities
25 August 2020
Several security issues were fixed in PostgreSQL.
Noah Misch discovered that PostgreSQL incorrectly handled the search_path
setting when used with logical replication. A remote attacker could
possibly use this issue to execute arbitrary SQL code. This issue only
affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-14349)
Andres Freund discovered that PostgreSQL incorrectly handled search path
elements in CREATE EXTENSION. A remote attacker could possibly use this
issue to execute arbitrary SQL code. (CVE-2020-14350)
The problem can be corrected by updating your system to the following package versions:
This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart PostgreSQL to
make all the necessary changes.
