Detail

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

- Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in PostgreSQL.

Software Description: - postgresql-9.6: Object-relational SQL database - postgresql-9.5: Object-relational SQL database - postgresql-9.3: Object-relational SQL database

Details:

David Rowley discovered that PostgreSQL incorrectly handled memory when processing certain JSON functions. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2017-15098)

Dean Rasheed discovered that PostgreSQL incorrectly enforced SELECT privileges when processing INSERT ... ON CONFLICT DO UPDATE commands. A remote attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 16.04 LTS, Ubuntu 17.04 and Ubuntu 17.10.

Update instructions:

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

Ubuntu 17.10:
postgresql-9.6 9.6.6-0ubuntu0.17.10

Ubuntu 17.04:
postgresql-9.6 9.6.6-0ubuntu0.17.04

Ubuntu 16.04 LTS:
postgresql-9.5 9.5.10-0ubuntu0.16.04

Ubuntu 14.04 LTS:
postgresql-9.3 9.3.20-0ubuntu0.14.04

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.
