This appears to be due to the format of the string being passed to
strtonum(). ap_strtol() was tolerant of it. It's being passed the
string from the Range: header.
For example, the following valid request (taken directly from sniffing a
wget session).
GET /testfile HTTP/1.0
Range: bytes=300417024-
This ends up following the code path of the first strtonum() call around
line 159 in http_protocol.c in the parse_byterange() function. The
string passed to strtonum to convert (r->range) not only contains the
number from the header, but the trailing dash ("300417024-"), which
strtonum does not like. As strtonum fails, the start offset is set to
0.
This bug should be present on a 64-bit arch as well.
