Details
Check Text (C-215414r991589_chk)
Check the version of "sendmail" installed on the system using:
# echo \$Z | /usr/sbin/sendmail -bt -d0
The above command should yield the following output:
Version AIX7.2/8.14.4
Compiled with: DNSMAP LDAPMAP LDAP_REFERRALS LOG MAP_REGEX MATCHGECOS
MILTER MIME7TO8 MIME8TO7 NAMED_BIND NDBM NETINET NETINET6
NETUNIX NEWDB NIS NISPLUS PIPELINING SCANF USERDB USE_LDAP_INIT
USE_TTYPATH XDEBUG
If the "sendmail" reported version is less than "8.6", this is a finding.
Fix Text (F-16610r294694_fix)
Obtain and install a more recent version of "Sendmail", which does not implement the DEBUG feature.
