- Details
-
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.
