Description

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: Run sudo ua fix USN-5440-1 to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: postgresql-server-dev-10 – 10.21-0ubuntu0.18.04.1 postgresql-10 – 10.21-0ubuntu0.18.04.1 libecpg6 – 10.21-0ubuntu0.18.04.1 libpq5 – 10.21-0ubuntu0.18.04.1 libpgtypes3 – 10.21-0ubuntu0.18.04.1 postgresql-pltcl-10 – 10.21-0ubuntu0.18.04.1 postgresql-plperl-10 – 10.21-0ubuntu0.18.04.1 libecpg-dev – 10.21-0ubuntu0.18.04.1 postgresql-plpython3-10 – 10.21-0ubuntu0.18.04.1 libpq-dev – 10.21-0ubuntu0.18.04.1 postgresql-plpython-10 – 10.21-0ubuntu0.18.04.1 postgresql-doc-10 – 10.21-0ubuntu0.18.04.1 postgresql-client-10 – 10.21-0ubuntu0.18.04.1 libecpg-compat3 – 10.21-0ubuntu0.18.04.1 No subscription required
