CVE-2017-1000101 (GCVE-0-2017-1000101)

Vulnerability from cvelistv5 – Published: 2017-10-04 01:00 – Updated: 2026-04-16 13:45
VLAI
Summary
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`.
