Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04 - Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in PostgreSQL.

Software Description: - postgresql-11: object-relational SQL database - postgresql-10: Object-relational SQL database - postgresql-9.5: Object-relational SQL database

Details:

It was discovered that PostgreSQL incorrectly handled partition routing. A remote user could possibly use this issue to read arbitrary bytes of server memory. This issue only affected Ubuntu 19.04. (CVE-2019-10129)

Dean Rasheed discovered that PostgreSQL incorrectly handled selectivity estimators. A remote attacker could possibly use this issue to bypass row security policies. (CVE-2019-10130)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.04:
postgresql-11 11.3-0ubuntu0.19.04.1

Ubuntu 18.10:
postgresql-10 10.8-0ubuntu0.18.10.1

Ubuntu 18.04 LTS:
postgresql-10 10.8-0ubuntu0.18.04.1

Ubuntu 16.04 LTS:
postgresql-9.5 9.5.17-0ubuntu0.16.04.1

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.
