    CVE-2023-44487

    Summary: nginx security update

    Details: NGINX is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. Security Fix(es): The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.(CVE-2023-44487)
