{"id":"UBUNTU-CVE-2015-9258","details":"In Docker Notary before 0.1, gotuf/signed/verify.go has a Signature Algorithm Not Matched to Key vulnerability. Because an attacker controls the field specifying the signature algorithm, they might (for example) be able to forge a signature by forcing a misinterpretation of an RSA-PSS key as Ed25519 elliptic-curve data.","modified":"2025-07-17T16:52:26Z","published":"2018-03-31T21:29:00Z","withdrawn":"2025-07-18T16:43:21Z","upstream":["CVE-2015-9258"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2015-9258"},{"type":"REPORT","url":"https://docs.docker.com/notary/changelog/"},{"type":"REPORT","url":"https://github.com/theupdateframework/notary/blob/master/docs/resources/ncc_docker_notary_audit_2015_07_31.pdf"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2015-9258"}],"affected":[{"package":{"name":"notary","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/notary@0.1~ds1-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.1~ds1-1"}]}],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"golang-github-docker-notary-dev","binary_version":"0.1~ds1-1"},{"binary_name":"notary","binary_version":"0.1~ds1-1"},{"binary_name":"notary-dbgsym","binary_version":"0.1~ds1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2015/UBUNTU-CVE-2015-9258.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
