The version of mutt installed on the remote host is prior to 1.5.21-29. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1892 advisory.

    Mutt before 1.14.3 allows an IMAP fcc/postpone man-in-the-middle attack via a PREAUTH response.
    (CVE-2020-14093)

    Mutt before 1.14.3 proceeds with a connection even if, in response to a GnuTLS certificate prompt, the     user rejects an expired intermediate certificate. (CVE-2020-14154)

    Mutt before 1.14.4 and NeoMutt before 2020-06-19 have 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 man-     in-the-middle attacker) and evaluates it in a TLS context, aka response injection. (CVE-2020-14954)

    Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that  was processed if an IMAP server's     initial server response was invalid. The connection was not properly closed, and the code could continue     attempting to authenticate. This could result in authentication credentials being exposed on an     unencrypted connection, or to a machine-in-the-middle. (CVE-2020-28896)

    rfc822.c in Mutt through 2.0.4 allows remote attackers to cause a denial of service (mailbox     unavailability) by sending email messages with sequences of semicolon characters in RFC822 address fields     (aka terminators of empty groups). A small email message from the attacker can cause large memory     consumption, and the victim may then be unable to see email messages from other persons. (CVE-2021-3181)

    A flaw was found in mutt. When reading unencoded messages, mutt uses the line length from the untrusted     input without any validation. This flaw allows an attacker to craft a malicious message, which leads to an     out-of-bounds read, causing data leaks that include fragments of other unrelated messages. (CVE-2022-1328)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
