Important: haproxy security update (Amazon Linux 2023)

Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2026-110354: A flaw was found in haproxy. A remote, unauthenticated attacker can trigger a denial of service (DoS) by sending a specially crafted HTTP/1.1 chunked request. When processing the request, the parser repeatedly re-evaluates the same data without making forward progress, trapping the worker thread in a continuous loop that consumes 100% CPU. Multiple malicious requests can exhaust all worker threads, rendering the proxy completely unresponsive until restarted.
