Summary

CVE-2020-14093

Mutt allowed an IMAP fcc/postpone man-in-the-middle attack via a
PREAUTH response.

CVE-2020-14954

Mutt had a STARTTLS buffering issue that affected IMAP, SMTP, and
POP3. When a server had sent a "begin TLS" response, the client read
additional data (e.g., from a man-in-the-middle attacker) and
evaluated it in a TLS context, aka "response injection."

For Debian 8 "Jessie", these problems have been fixed in version
1.5.23-3+deb8u2.

We recommend that you upgrade your mutt packages.
