Comment 6 Jason Shepherd 2020-06-09 20:35:30 UTC 
The impact of this vulnerability was reduced to moderate because of the challenges faced by an attacker trying to exploit this vulnerability. In addition to only being able to thwart HTTPS requests which reuse an existing HTTPS session, they would need to be in a privileged network position, such as on the same Wifi network in order to serve malicious HTTPS requests in place of legitimate ones.
Comment 9 Jason Shepherd 2020-06-09 20:40:13 UTC 
Statement:

This issue only affects the TLS 1.2 protocol, not TLS 1.3. This issue does not affect NodeJS 10.

Red Hat Quay installed NodeJS as a dependency of Yarn. It does not use NodeJS at runtime, but executes Javascript on the client's browser instead. Therefore the impact of this vulnerability on Red Hat Quay is low.
Comment 13 Laurie Morse 2020-06-15 18:15:10 UTC 
What is the ETA for this fix with RHEL 8 and NodeJS 12?  We have a release deadline for July and this CVE is needed.
