Description Adam Mariš 2017-08-04 09:18:13 UTC
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.

Affected versions: curl 7.34.0 up to and including 7.54.1

This flaw only affects the curl command line tool, not the libcurl library.
