   * Add 13_check_smtp_greeting.dpatch (Closes: #611914), thanks Daniel Piddock
     for spotting and Holger Weiss for providing a fix
     - Abort immediately if we don't receive a server greeting or if the
       greeting doesn't contain the "--expect"ed string (by default: "220")
       instead of blindly sending the EHLO/HELO line.
+  * Add 14_check_icmp_multiple_ips.dpatch (Closes: #623702), thanks Max Kosmach
+    for spotting and Sebastian Harl for providing a fix
+    - When specifying a host-name on the command line, each of its IPs is added
+      to the host table (and each one is pinged). So, the buffer has to be large
+      enough to hold all of the respective host objects. (argc - 1) only fits
+      hosts with a single IP.
   * Move libraries linked at compile time against checks of
     nagios-plugins-standard from Depends to Recommends (Closes: #569028)
     - Add slightly modified bin/gen_plugin_deps.pl from collectd source package
