NVD Description

Note: Versions mentioned in the description apply only to the upstream libetpan package and not the libetpan package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

LibEtPan through 1.9.4, as used in MailCore 2 through 0.6.3 and other products, has a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data (e.g., from a meddler-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection."
