nghttp2 — Vulnerabilities & Security Advisories 5

Nghttp2 serves as an HTTP/2 implementation library, enabling efficient web communication for applications and servers. Historically, it has been susceptible to remote code execution vulnerabilities due to buffer overflows and integer overflows, along with denial-of-service flaws from improper handling of input data. While no major public incidents have been widely documented, the four recorded CVEs highlight potential risks in memory management and parsing logic. Its C codebase and complex protocol implementation contribute to ongoing security challenges, requiring careful integration and regular updates to mitigate risks in environments handling high-volume HTTP/2 traffic.
