The remote host is affected by the vulnerability described in GLSA-202402-18 (Exim: Multiple Vulnerabilities)

  - Exim before 4.97.1 allows SMTP smuggling in certain PIPELINING/CHUNKING configurations. Remote attackers     can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address,     allowing bypass of an SPF protection mechanism. This occurs because Exim supports <LF>.<CR><LF> but some     other popular e-mail servers do not. (CVE-2023-51766)

  - NTLM Challenge Out-Of-Bounds Read Information Disclosure Vulnerability [epel-all] (CVE-2023-42114)

  - AUTH Out-Of-Bounds Write Remote Code Execution Vulnerability [epel-all] (CVE-2023-42115)

  - Exim SMTP Challenge Stack-based Buffer Overflow Remote Code Execution Vulnerability (CVE-2023-42116,     CVE-2023-42117)

  - dnsdb Out-Of-Bounds Read Information Disclosure Vulnerability [epel-all] (CVE-2023-42119)

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