## 2017-07-11, Version 4.8.4 'Argon' (Maintenance), @MylesBorins

This is a security release. All Node.js users should consult the security release summary at https://nodejs.org/en/blog/vulnerability/july-2017-security-releases/ for details on patched vulnerabilities.

### Notable Changes

* **build**:

- Disable V8 snapshots - The hashseed embedded in the snapshot is currently the same for all runs of the binary. This opens node up to collision attacks which could result in a Denial of Service. We have temporarily disabled snapshots until a more robust solution is found (Ali Ijaz Sheikh)

* **deps**:

- CVE-2017-1000381 - The c-ares function ares_parse_naptr_reply(), which is used for parsing NAPTR responses, could be triggered to read memory outside of the given input buffer if the passed in DNS response packet was crafted in a particular way. This patch checks that there is enough data for the required elements of an NAPTR record (2 int16, 3 bytes for string lengths) before processing a record. (David Drysdale)
