CVE-2025-5399

Due to a mistake in libcurl’s WebSocket code, a malicious server can send a
particularly crafted packet which makes libcurl get trapped in an endless
busy-loop.

There is no other way for the application to escape or exit this loop other
than killing the thread/process.

This might be used to DoS libcurl-using application.
