+Subject: [PATCH] network plugin: Fix endless loop DOS in parse_packet()
+
+When correct 'Signature part' is received by Collectd, configured without
+AuthFile option, condition for endless loop occurs due to missing increase
+of pointer to next unprocessed part.
+
+Fixes: CVE-2017-7401
+
+Signed-off-by: Florian Forster <octo@collectd.org>
