Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- Nodemailer versions before 8.0.5 contain an SMTP command injection vulnerability in the transport name option used in EHLO/HELO commands. The name parameter is concatenated directly into SMTP commands without sanitizing carriage return and line feed characters, allowing attackers to inject arbitrary SMTP commands for email spoofing and phishing attacks.

Note that Nessus relies on the presence of the package as reported by the vendor.
