{"id":"UBUNTU-CVE-2016-8616","details":"A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password.","modified":"2026-01-30T00:55:38.913206Z","published":"2016-11-02T00:00:00Z","related":["USN-3123-1"],"upstream":["CVE-2016-8616"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-8616"},{"type":"REPORT","url":"https://curl.haxx.se/docs/adv_20161102B.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3123-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2016-8616"}],"affected":[{"package":{"name":"curl","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/curl@7.35.0-1ubuntu2.10?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.35.0-1ubuntu2.10"}]}],"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"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"curl","binary_version":"7.35.0-1ubuntu2.10"},{"binary_name":"libcurl3","binary_version":"7.35.0-1ubuntu2.10"},{"binary_name":"libcurl3-gnutls","binary_version":"7.35.0-1ubuntu2.10"},{"binary_name":"libcurl3-nss","binary_version":"7.35.0-1ubuntu2.10"},{"binary_name":"libcurl4-gnutls-dev","binary_version":"7.35.0-1ubuntu2.10"},{"binary_name":"libcurl4-nss-dev","binary_version":"7.35.0-1ubuntu2.10"},{"binary_name":"libcurl4-openssl-dev","binary_version":"7.35.0-1ubuntu2.10"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2016/UBUNTU-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/curl@7.47.0-1ubuntu2.2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.47.0-1ubuntu2.2"}]}],"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"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"curl","binary_version":"7.47.0-1ubuntu2.2"},{"binary_name":"libcurl3","binary_version":"7.47.0-1ubuntu2.2"},{"binary_name":"libcurl3-gnutls","binary_version":"7.47.0-1ubuntu2.2"},{"binary_name":"libcurl3-nss","binary_version":"7.47.0-1ubuntu2.2"},{"binary_name":"libcurl4-gnutls-dev","binary_version":"7.47.0-1ubuntu2.2"},{"binary_name":"libcurl4-nss-dev","binary_version":"7.47.0-1ubuntu2.2"},{"binary_name":"libcurl4-openssl-dev","binary_version":"7.47.0-1ubuntu2.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2016/UBUNTU-CVE-2016-8616.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"},{"type":"Ubuntu","score":"low"}]}
