code then tries to skip the chunk in pieces of 512 bytes by using the
MIN() macro, but ends up passing the negative chunk length to
connect.c:fd_read(). As fd_read() takes an int argument, the high
32 bits of the chunk length are discarded, leaving fd_read() with
a completely attacker controlled length argument (CVE-2017-13089).
The retr.c:fd_read_body() function is called when processing OK
