According to the versions of the mutt package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
Mutt before 1.14.3 allows an IMAP fcc/postpone man-in-the-middle attack via a PREAUTH response.(CVE-2020-14093)
Mutt before 1.14.4 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 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)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
