It was discovered that OpenVPN incorrectly handled certain data channel v2
packets. A remote attacker could possibly use this issue to inject packets
using a victim’s peer-id. This issue only affected Ubuntu 18.04 LTS and
Ubuntu 20.04 LTS. (CVE-2020-11810)

It was discovered that OpenVPN incorrectly handled deferred authentication.
When a server is configured to use deferred authentication, a remote
attacker could possibly use this issue to bypass authentication and access
control channel data. (CVE-2020-15078)
