CVE-2023-51765 3 Freebsd, Redhat, Sendmail 3 Freebsd, Enterprise Linux, Sendmail 2024-01-09 N/A 5.3 MEDIUM
sendmail through 8.17.2 allows SMTP smuggling in certain 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 sendmail supports <LF>.<CR><LF> but some other popular e-mail servers do not. This is resolved in 8.18 and later versions with 'o' in srv_features.
