Summary
libwebsockets security update
Details

Libwebsockets (LWS) is a flexible, lightweight pure C library for implementing modern network protocols easily with a tiny footprint, using a nonblocking event loop.

Security Fix(es):

Use After Free vulnerability exists in the WebSocket server implementation in lws_handshake_server in warmcat libwebsockets. In specific configurations where the user provides a callback function that handles LWS_CALLBACK_HTTP_CONFIRM_UPGRADE, an attacker may achieve denial of service.(CVE-2025-11677)

Stack-based Buffer Overflow in lws_adns_parse_label in warmcat libwebsockets allows, when the LWS_WITH_SYS_ASYNC_DNS flag is enabled during compilation, to overflow the label_stack, when the attacker is able to sniff a DNS request in order to craft a response with a matching id containing a label longer than the maximum.(CVE-2025-11678)
