An issue was discovered in OpenVPN 2.4.x before 2.4.9. An attacker can
inject a data channel v2 (P_DATA_V2) packet using a victim's peer-id.
Normally such packets are dropped, but if this packet arrives before the
data channel crypto parameters have been initialized, the victim's
connection will be dropped. This requires careful timing due to the small
time window (usually within a few seconds) between the victim client
connection starting and the server PUSH_REPLY response back to the client.
This attack will only work if Negotiable Cipher Parameters (NCP) is in
use (CVE-2020-11810).
The openvpn package has been updated to version 2.4.9, fixing the issue
and other bugs. See the upstream release notes for details.");
