Description and CVSS Score
A bug exists in Node.js versions 4.0.0 to 4.1.1 whereby an external attacker can cause a denial of service. The severity of this issue is high (see CVSS scoring below) and users of the affected versions should plan to upgrade when a fix is made available.
- Versions 0.10 and 0.12 of Node.js are _not affected_.
- Versions 4.0.0, 4.1.0 and 4.1.1 of Node.js are _vulnerable_.
- Versions 1 and 2 of io.js are _not affected_ but remain unsupported and users of these versions are encouraged to migrate to Node.js v4 at their earliest convenience.
- Version 3 of io.js is _vulnerable_ and while io.js v3 is unsupported, a patch release with a fix will be made available some time next week. Users of io.js v3 are encouraged to migrate to Node.js v4 as a matter of priority.
Full details of this vulnerability are embargoed until a new v4.x release is made available on Monday the 5th of October 2015, UTC.
