CVE-2025-62504 (CNNVD-202510-2282)
中文标题:
Envoy 资源管理错误漏洞
英文标题:
Envoy Lua filter use-after-free when oversized rewritten response body causes crash
漏洞描述
中文描述:
Envoy是Enphase开源的一款用于连接智能家居设备的网关程序。 Envoy 1.36.2之前版本、1.35.6之前版本、1.34.10之前版本和1.33.12之前版本存在资源管理错误漏洞,该漏洞源于Lua过滤器存在释放后重用,可能导致拒绝服务。
英文描述:
Envoy is an open source edge and service proxy. Envoy versions earlier than 1.36.2, 1.35.6, 1.34.10, and 1.33.12 contain a use-after-free vulnerability in the Lua filter. When a Lua script executing in the response phase rewrites a response body so that its size exceeds the configured per_connection_buffer_limit_bytes (default 1MB), Envoy generates a local reply whose headers override the original response headers, leaving dangling references and causing a crash. This results in denial of service. Updating to versions 1.36.2, 1.35.6, 1.34.10, or 1.33.12 fixes the issue. Increasing per_connection_buffer_limit_bytes (and for HTTP/2 the initial_stream_window_size) or increasing per_request_buffer_limit_bytes / request_body_buffer_limit can reduce the likelihood of triggering the condition but does not correct the underlying memory safety flaw.
