GMS-2017-197: Regular Expression Denial of Service

September 8, 2017

charset is vulnerable to regular expression denial of service. Input of around k 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 kb so the impact of the ReDoS is relatively low.
