CVE-2017-1000101

curl supports “globbing” of URLs, in which a user can pass a numerical
range to have the tool iterate over those numbers to do a sequence of
transfers. In the globbing function that parses the numerical range, there
was an omission that made curl read a byte beyond the end of the URL if
given a carefully crafted, or just wrongly written, URL. The URL is stored
in a heap based buffer, so it could then be made to wrongly read something
else instead of crashing. An example of a URL that triggers the flaw would
be http://ur%20[0-60000000000000000000.
