How to fix?

There is no fixed version for Debian:10 citadel.

NVD Description

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

An issue was discovered in Citadel through webcit-932. A meddler-in-the-middle attacker can fixate their own session during the cleartext phase before a STARTTLS command (a violation of "The STARTTLS command is only valid in non-authenticated state." in RFC2595). This potentially allows an attacker to cause a victim's e-mail messages to be stored into an attacker's IMAP mailbox, but depends on details of the victim's client behavior.
