Hi,

The following vulnerability was published for libetpan.

CVE-2020-15953[0]:
| 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."


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
