{"id":"UBUNTU-CVE-2020-25650","details":"A flaw was found in the way the spice-vdagentd daemon handled file transfers from the host system to the virtual machine. Any unprivileged local guest user with access to the UNIX domain socket path `/run/spice-vdagentd/spice-vdagent-sock` could use this flaw to perform a memory denial of service for spice-vdagentd or even other processes in the VM system. The highest threat from this vulnerability is to system availability. This flaw affects spice-vdagent versions 0.20 and previous versions.","modified":"2026-01-30T01:53:38.508545Z","published":"2020-11-03T00:00:00Z","related":["USN-4617-1"],"upstream":["CVE-2020-25650"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-25650"},{"type":"REPORT","url":"https://www.openwall.com/lists/oss-security/2020/11/04/1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4617-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-25650"}],"affected":[{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent@0.15.0-1.3?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.15.0-1.3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.15.0-1.3","binary_name":"spice-vdagent"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-25650.json"}},{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent@0.17.0-1ubuntu2.2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.17.0-1ubuntu2.2"}]}],"versions":["0.17.0-1ubuntu1","0.17.0-1ubuntu2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"0.17.0-1ubuntu2.2","binary_name":"spice-vdagent"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-25650.json"}},{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent@0.19.0-2ubuntu0.2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.19.0-2ubuntu0.2"}]}],"versions":["0.19.0-2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"0.19.0-2ubuntu0.2","binary_name":"spice-vdagent"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-25650.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"low"}]}
