Description Andrej Nemec 2017-09-21 09:43:32 UTC 
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.

Comment 15 Jason Shepherd 2018-06-13 21:29:08 UTC 
NodeJS is shipped in Openshift Enterprise 3.9 as ImageStreams. Those ImageStreams are the RH Software Collection images. Setting Openshift Enterprise 3 as not affected.
Comment 18 Jason Shepherd 2021-03-28 22:20:41 UTC 
Statement:

Red Hat Quay include nodejs-tough-cookie as a build time dependency of protractor. It's no included in the runtime code, and is therefore not affected by this vulnerability.
