 ### Fixes
 * Fix for systemd-backend: fail2ban hits the ulimit (out of file descriptors), see gh-991.
   Partially back-ported from v.0.10.
+* filter.d/apache-overflows.conf:
+    - Fixes resources greedy expression (see gh-1790);
+    - Rewritten without end-anchor ($), because of potential vulnerability on very long URLs.

 # DEV Notes:
+#
+# [sebres] Because this apache-log could contain very long URLs (and/or referrer), 
+#          the parsing of it anchored way may be very vulnerable (at least as regards 
+#          the system resources, see gh-1790). Thus rewritten without end-anchor ($).
