NGINX Updates Mitigate the August 2019 HTTP/2 Vulnerabilities
Today we are releasing updates to NGINX Open Source and NGINX Plus in response to the vulnerabilities recently discovered in the HTTP/2 protocol. We strongly recommend upgrading all systems that have HTTP/2 enabled.
In May 2019, researchers at Netflix discovered a number of security vulnerabilities in several HTTP/2 server implementations. These were responsibly reported to each of the vendors and maintainers concerned. NGINX was vulnerable to three attack vectors, as detailed in the following CVEs:
- CVE-2019-9511 (Data dribble)
- CVE-2019-9513 (Resource loop)
- CVE-2019-9516 (Zero‑length headers leak)
We have addressed these vulnerabilities, and added other HTTP/2 security safeguards, in the following NGINX versions:
- NGINX 1.16.1 (stable)
- NGINX 1.17.3 (mainline)
- NGINX Plus R18 P1
