+Subject: [PATCH] Avoid post-rewrite URI to path mapping with alias
+
+Previously, after a "rewrite" had changed the URI, and before a new
+location was chosen, the new URI might not match the current location
+prefix.  This becomes a problem when the location uses "alias", which
+is why normally such inconsistency is detected by checking the
+r->valid_location flag.  Meanwhile this flag only handles the
+inconsistency when using the "break" directive or parameter.  However
+in absence of those, there's still an inconsistency window from URI
+change up until the end of the current set of rewrite directives.
+URI to path mapping within this window might result in a buffer
+overflow if location's prefix was longer than the rewritten URI.
+
+The following example resulted in a buffer overflow with the request
+"/foo/1":
+
+location /foo/ {
+    alias /bar/;
+    rewrite ^/foo/.*$ /x;
+    return 200 $request_filename;
+}
+
+Alternatively, $request_filename might be used in access log format,
+"set", "if", "add_header", etc.
+
+The fix is to reject URI mapping in ngx_http_map_uri_to_path() if the
+r->uri_changed flag is set.
