Updated sendmail packages fix security vulnerability

Publication date: 16 Jul 2024
Modification date: 16 Jul 2024
Type: security
Affected Mageia releases : 9
CVE: CVE-2023-51765

Description

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
. but some other popular e-mail servers do not. This is
resolved in 8.18 and later versions with 'o' in srv_features.
