 'cwe': ['CWE-703', 'CWE-835'], 'message': 'libvncclient: handle half-open TCP connections

When a connection is not reset properly at the TCP level (e.g. sudden
power loss or process crash) the TCP connection becomes half-open and
read() always returns -1 with errno = EAGAIN while select() always
returns 0. This leads to an infinite loop and can be fixed by closing
the connection after a certain number of retries (based on a timeout)
has been exceeded.'
