Summary
Important: nginx:1.14 security update
Details

Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 (Post Office Protocol 3) and IMAP protocols, with a focus on high concurrency, performance and low memory usage.

Security Fix(es):

  • HTTP/2: large amount of data request leads to denial of service (CVE-2019-9511)

  • HTTP/2: flood using PRIORITY frames resulting in excessive resource consumption (CVE-2019-9513)

  • HTTP/2: 0-length headers leads to denial of service (CVE-2019-9516)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
