{"id":"CVE-2017-1000101","url":"https://www.cyber-defence.io/tools/cve/CVE-2017-1000101","generatedAt":"2026-10-28T22:41:52.297Z","title":"The URL is stored in a heap based buffer, so it could then be made to wrongly read something else instead of crashing.","description":"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`.","published":"2017-10-05T01:29:04.000Z","lastModified":"2026-06-17T00:58:44.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},"cwe":["CWE-119"],"affected":["haxx/curl"],"epss":{"score":0.03724,"percentile":0.89744,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (3.72%).
