USN-4027-1: PostgreSQL vulnerability
postgresql-10, postgresql-11 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.04
- Ubuntu 18.10
- Ubuntu 18.04 LTS
Summary
PostgreSQL could be made to crash or run programs if it received specially
crafted network traffic.
Software Description
- postgresql-11 – Object-relational SQL database
- 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.
