How to fix?

Upgrade Debian:unstable octavia to version 18.0.0-4 or higher.

NVD Description

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

In OpenStack Octavia before 18.0.1, the Amphora provider driver did not validate the listener and pool tls_ciphers field for control characters. The value is written verbatim into the HAProxy configuration generated on the amphora, and thus an authenticated project member who owns a TLS-enabled load balancer can embed a newline and inject arbitrary HAProxy configuration directives. Only deployments using the Amphora provider are affected.
