USN-4027-1: PostgreSQL vulnerability
20 June 2019

postgresql-10, postgresql-11 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:

  o Ubuntu 19.04
  o Ubuntu 18.10
  o Ubuntu 18.04 LTS

Summary

PostgreSQL could be made to crash or run programs if it received specially
crafted network traffic.

Software Description

  o postgresql-11 - Object-relational SQL database
  o postgresql-10 - Object-relational SQL database

Details

Alexander Lakhin discovered that PostgreSQL incorrectly handled authentication.
An authenticated attacker or a rogue server could use this issue to cause
PostgreSQL to crash, resulting in a denial of service, or possibly execute
arbitrary code. The default compiler options for affected releases should
reduce the vulnerability to a denial of service.

Update instructions

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

Ubuntu 19.04
    postgresql-11 - 11.4-0ubuntu0.19.04.1
Ubuntu 18.10
    postgresql-10 - 10.9-0ubuntu0.18.10.1
Ubuntu 18.04 LTS
    postgresql-10 - 10.9-0ubuntu0.18.04.1

To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .

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.
