Hi, The following vulnerability was published for exim4. CVE-2023-51766[0]: | Exim through 4.97 allows SMTP smuggling in certain configurations. | Remote attackers can use a published exploitation technique to | inject e-mail messages that appear to originate from the Exim | server, allowing bypass of an SPF protection mechanism. This occurs | because Exim supports <LF>.<CR><LF> but some other popular e-mail | servers do not. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
