mongodb vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

MongoDB could provide unintended access.

Software Description:
- mongodb: Document-oriented database

Details:

MongoDB would fail to properly invalidate existing sessions for deleted
users. This could allow a remote authenticated attacker to gain elevated
privileges if their user account was recreated with elevated privileges.

Update instructions:

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

Ubuntu 20.04 LTS:
  mongodb-clients                 1:3.6.9+really3.6.8+90~g8e540c0b6d-0ubuntu5.2
