NVD Description

Note: Versions mentioned in the description apply only to the upstream openvpn package and not the openvpn package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

OpenVPN, when using a 64-bit block cipher, makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTP-over-OpenVPN session using Blowfish in CBC mode, aka a "Sweet32" attack.
