Summary:

Several security issues were fixed in PostgreSQL.

Software Description:

- 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.
