USN-5440-1: PostgreSQL vulnerability

24 May 2022

PostgreSQL could be made to execute commands as the superuser.

Releases

Packages

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 22.04
Ubuntu 21.10
Ubuntu 20.04
Ubuntu 18.04

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.
