Resolved a buffer overflow bug in ngx_http_graphite_location() when parsing uri entirely made up of underscores. The loop incorrectly traverses past the buffer's boundary:
while (split->len > 0 && split->data[0] == '_') {
split->data++;
split->len--;
}
Later, it writes a '_' character outside of the buffer:
if (split->len == 0) {
split->data[split->len++] = '_';
}
This problem occurs with the uri: "/".
