Description Andrej Nemec 2017-09-21 05:43:32 EDT 
It was found that the tough-cookie module is vulnerable to regular expression denial of service. Input of around 50k characters is required for a slow down of around 2 seconds.

Unless node was compiled using the -DHTTP_MAX_HEADER_SIZE= option the default header max length is 80kb so the impact of the ReDoS is limited to around 7.3 seconds of blocking.
