medium Tenable Self-Hosted Container Security Plugin ID 408214

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)
