There is no fixed version for Centos:6 sendmail-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sendmail-devel package and not the sendmail-devel package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

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.
