The CERT Coordination Center (CERT/CC) has released information on vulnerabilities affecting HTTP/2 implementations. An 
attacker could exploit these vulnerabilities to cause a denial-of-service (DoS) condition. Attacks can consume 
excessive system resources and lead to distributed DoS (DDoS) attacks.

The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and administrators to review CERT/CCs 
Vulnerability Note VU#605641 [ https://www.kb.cert.org/vuls/id/605641/ ] for more information and refer to vendors for 
updates.
