The http.c:skip_short_body() function is called in some circumstances, such
as when processing redirects. When the response is sent chunked in wget
before 1.19.2, the chunk parser uses strtol() to read each chunk’s length,
but doesn’t check that the chunk length is a non-negative number. The 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.
