USN-5676-1: PostgreSQL vulnerability

Releases

• Ubuntu 16.04 ESM

Packages

• postgresql-9.5 - Object-relational SQL database

Details

Alexander Lakhin discovered that PostgreSQL incorrectly handled the
security restricted operation sandbox when a privileged user is maintaining
another user’s objects. An attacker having permission to create non-temp
objects can use this issue to execute arbitrary commands as the superuser.

Update instructions

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

Ubuntu 16.04

• postgresql-9.5 - 9.5.25-0ubuntu0.16.04.1+esm2
  Available with Ubuntu Pro

After a standard system update you need to restart PostgreSQL to
make all the necessary changes.
