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

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

According to its banner, the version of Exim running on the remote host is prior to 4.96.1. It is, therefore, potentially affected by multiple vulnerabilities:

    - NTLM Challenge Out-Of-Bounds Read (CVE-2023-42114)

    - AUTH Out-Of-Bounds Write (CVE-2023-42115)

    - SMTP Challenge Stack-based Buffer Overflow CVE-2023-42116)

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

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6411-1 advisory.

    It was discovered that Exim incorrectly handled certain challenge requests. A remote attacker could     possibly use this issue to perform out-of-bounds reads, resulting in information leakage. (CVE-2023-42114)

    It was discovered that Exim incorrectly handled validation of user-supplied data. A remote attacker could     possibly use this issue to perform out-of-bounds writes, resulting in arbitrary code execution. This issue     only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 23.04. (CVE-2023-42115)

  - A vulnerability was found in Exim and classified as problematic. This issue affects some unknown     processing of the component Regex Handler. The manipulation leads to use after free. The name of the patch     is 4e9ed49f8f12eb331b29bd5b6dc3693c520fddc2. It is recommended to apply a patch to fix this issue. The     identifier VDB-211073 was assigned to this vulnerability.

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

  - 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)

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