Regular Expression Denial of Service in tough-cookie

Affected versions of tough-cookie are susceptible to a regular expression denial of service.

The amplification on this vulnerability is relatively low - it takes around 2 seconds for the engine to execute on a malicious input which is 50,000 characters in length.

If node was compiled using the -DHTTP_MAX_HEADER_SIZE however, the impact of the vulnerability can be significant, as the primary limitation for the vulnerability is the default max HTTP header length in node.
