+Subject: [PATCH] acl: use hostspec parser to disallow suffix hostname matches
+
+the existing ad-hoc parsing in acl.c allowed an attacker to
+use e.g. an "untrusted.net" domain name to access a reachable
+tinyproxy instance if it had an allow list entry for "trusted.net".
+
+exploiting it would require that the attacker has prior knowledge
+of the instance's configuration or is damn good at guessing and
+well-budgeted to register lots of potentially matching domains.
+
+fix by re-using the existing hardened hostspec parser.
+
+closes #627
+
+(cherry picked from commit 3991ac8f98c6a9f05b3265018b812dbf2ca92c28)
