Description
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."
