Beschreibung:Summary:
The remote host is missing an update for the 'postfix' package(s) announced via the SSA:2023-356-01 advisory.

Vulnerability Insight:
New postfix packages are available for Slackware 15.0 and -current to
fix a security issue.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/postfix-3.6.13-i586-1_slack15.0.txz: Upgraded.
Security: this release adds support to defend against an email spoofing
attack (SMTP smuggling) on recipients at a Postfix server. Sites
concerned about SMTP smuggling attacks should enable this feature on
Internet-facing Postfix servers. For compatibility with non-standard
clients, Postfix by default excludes clients in mynetworks from this
countermeasure.
The recommended settings are:
# Optionally disconnect remote SMTP clients that send bare newlines,
# but allow local clients with non-standard SMTP implementations
# such as netcat, fax machines, or load balancer health checks.
#
smtpd_forbid_bare_newline = yes
smtpd_forbid_bare_newline_exclusions = $mynetworks
The smtpd_forbid_bare_newline feature is disabled by default.
