{"id":"UBUNTU-CVE-2017-1000101","details":"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`.","modified":"2026-02-04T02:23:22.505580Z","published":"2017-10-04T00:00:00Z","related":["USN-3441-1"],"upstream":["CVE-2017-1000101"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-1000101"},{"type":"REPORT","url":"https://curl.haxx.se/docs/adv_20170809A.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3441-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-1000101"}],"affected":[{"package":{"name":"curl","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/curl@7.35.0-1ubuntu2.11?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.35.0-1ubuntu2.11"}]}],"versions":["7.32.0-1ubuntu1","7.33.0-1ubuntu1","7.34.0-1ubuntu1","7.35.0-1ubuntu1","7.35.0-1ubuntu2","7.35.0-1ubuntu2.1","7.35.0-1ubuntu2.2","7.35.0-1ubuntu2.3","7.35.0-1ubuntu2.5","7.35.0-1ubuntu2.6","7.35.0-1ubuntu2.7","7.35.0-1ubuntu2.8","7.35.0-1ubuntu2.9","7.35.0-1ubuntu2.10"],"ecosystem_specific":{"binaries":[{"binary_version":"7.35.0-1ubuntu2.11","binary_name":"curl"},{"binary_version":"7.35.0-1ubuntu2.11","binary_name":"libcurl3"},{"binary_version":"7.35.0-1ubuntu2.11","binary_name":"libcurl3-gnutls"},{"binary_version":"7.35.0-1ubuntu2.11","binary_name":"libcurl3-nss"},{"binary_version":"7.35.0-1ubuntu2.11","binary_name":"libcurl4-gnutls-dev"},{"binary_version":"7.35.0-1ubuntu2.11","binary_name":"libcurl4-nss-dev"},{"binary_version":"7.35.0-1ubuntu2.11","binary_name":"libcurl4-openssl-dev"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-1000101.json"}},{"package":{"name":"curl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/curl@7.47.0-1ubuntu2.3?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.47.0-1ubuntu2.3"}]}],"versions":["7.43.0-1ubuntu2","7.45.0-1ubuntu1","7.46.0-1ubuntu1","7.47.0-1ubuntu1","7.47.0-1ubuntu2","7.47.0-1ubuntu2.1","7.47.0-1ubuntu2.2"],"ecosystem_specific":{"binaries":[{"binary_version":"7.47.0-1ubuntu2.3","binary_name":"curl"},{"binary_version":"7.47.0-1ubuntu2.3","binary_name":"libcurl3"},{"binary_version":"7.47.0-1ubuntu2.3","binary_name":"libcurl3-gnutls"},{"binary_version":"7.47.0-1ubuntu2.3","binary_name":"libcurl3-nss"},{"binary_version":"7.47.0-1ubuntu2.3","binary_name":"libcurl4-gnutls-dev"},{"binary_version":"7.47.0-1ubuntu2.3","binary_name":"libcurl4-nss-dev"},{"binary_version":"7.47.0-1ubuntu2.3","binary_name":"libcurl4-openssl-dev"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-1000101.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"low"}]}
