{"id":"ALPINE-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":"2026-06-09T21:30:20.910856180Z","published":"2018-08-01T06:29:00.287Z","upstream":["CVE-2016-8616"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2016-8616"}],"affected":[{"package":{"name":"curl","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.2","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.49.1-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2016-8616.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.51.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALP
