USN-5676-1: PostgreSQL vulnerability
13 October 2022
PostgreSQL could be made to execute commands as the superuser.
Releases
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.
