NOTE: this issue is potentially relevant to persons outside Yubico who operate a self-hosted OTP validation service; the issue does NOT affect YubiCloud.","modified":"2025-10-24T04:48:21Z","published":"2020-03-05T23:15:00Z","upstream":["CVE-2020-10184"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-10184"},{"type":"REPORT","url":"https://www.yubico.com/support/security-advisories/ysa-2020-01/"},{"type":"REPORT","url":"https://github.com/Yubico/yubikey-val/commit/d0e4db3245deb5ce0c8d7d26069c78071a140286"},{"type":"REPORT","url":"https://github.com/Yubico/yubikey-val/releases/tag/yubikey-val-2.40"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-10184"}],"affected":[{"package":{"name":"yubikey-val","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/yubikey-val@2.33-1ubuntu1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.28-1","2.33-1","2.33-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.33-1ubuntu1","binary_name":"yubikey-val"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-10184.json"}},{"package":{"name":"yubikey-val","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/yubikey-val@2.38-2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.38-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.38-2","binary_name":"yubikey-val"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-10184.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
