{"id":"DEBIAN-CVE-2020-12062","details":"The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server. The victim must use the command scp -rp to download a file hierarchy containing, anywhere inside, this crafted subdirectory. NOTE: the vendor points out that \"this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol\" and \"utimes does not fail under normal circumstances.","modified":"2026-09-11T11:00:45.061647197Z","published":"2020-06-01T16:15:14.260Z","upstream":["CVE-2020-12062"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2020-12062"}],"affected":[{"package":{"name":"openssh","ecosystem":"Debian:12","purl":"pkg:deb/debian/openssh?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:8.3p1-1"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2020-12062.json"}},{"package":{"name":"openssh","ecosystem":"Debian:13","purl":"pkg:deb/debian/openssh?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:8.3p1-1"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2020-12062.json"}},{"package":{"name":"openssh","ecosystem":"Debian:14","purl":"pkg:deb/debian/openssh?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:8.3p1-1"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2020-12062.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
