Type: security
Affected Mageia releases: 9
CVE: CVE-2023-51765

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

resolved in 8.18 and later versions with 'o' in srv_features.
