[slackware-security]  postfix (SSA:2024-022-01)

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-3.6.14-i586-1_slack15.0.txz:  Upgraded.
  Security (inbound SMTP smuggling): with "smtpd_forbid_bare_newline
  = normalize" (default "no" for Postfix < 3.9), the Postfix
  SMTP server requires the standard End-of-DATA sequence
  ., and otherwise allows command or message
  content lines ending in the non-standard , processing
  them as if the client sent the standard .
  The alternative setting, "smtpd_forbid_bare_newline = reject"
  will reject any command or message that contains a bare
  , and is more likely to cause problems with legitimate
  clients.
  For backwards compatibility, local clients are excluded by
  default with "smtpd_forbid_bare_newline_exclusions =
  $mynetworks".
