{"id":"ALPINE-CVE-2019-17498","details":"In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server.","modified":"2026-09-09T06:17:50.098056506Z","published":"2019-10-21T22:15:10.523Z","upstream":["CVE-2019-17498"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-17498"}],"affected":[{"package":{"name":"libssh2","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/libssh2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2019-17498.json"}},{"package":{"name":"libssh2","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/l
