{"id":"UBUNTU-CVE-2025-4478","details":"A flaw was found in the FreeRDP used by Anaconda's remote install feature, where a crafted RDP packet could trigger a segmentation fault. This issue causes the service to crash and remain defunct, resulting in a denial of service. It occurs pre-boot and is likely due to a NULL pointer dereference. Rebooting is required to recover the system.","modified":"2026-04-22T16:03:27.808325Z","published":"2025-05-16T15:15:00Z","related":["USN-7624-1"],"upstream":["CVE-2025-4478"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-4478"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-4478"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7624-1"}],"affected":[{"package":{"name":"freerdp3","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/freerdp3@3.5.1+dfsg1-0ubuntu1.1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.1+dfsg1-0ubuntu1.1"}]}],"versions":["3.4.0+dfsg1-0ubuntu2","3.4.0+dfsg1-0ubuntu3","3.4.0+dfsg1-0ubuntu4","3.5.0+dfsg1-0ubuntu1","3.5.1+dfsg1-0ubuntu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"freerdp3-shadow-x11","binary_version":"3.5.1+dfsg1-0ubuntu1.1"},{"binary_name":"freerdp3-wayland","binary_version":"3.5.1+dfsg1-0ubuntu1.1"},{"binary_version":"3.5.1+dfsg1-0ubuntu1.1","binary_name":"freerdp3-x11"},{"binary_name":"libfreerdp-client3-3","binary_version":"3.5.1+dfsg1-0ubuntu1.1"},{"binary_version":"3.5.1+dfsg1-0ubuntu1.1","binary_name":"libfreerdp-server3-3"},{"binary_name":"libfreerdp-shadow-subsystem3-3","binary_version":"3.5.1+dfsg1-0ubuntu1.1"},{"binary_name":"libfreerdp-shadow3-3","binary_version":"3.5.1+dfsg1-0ubuntu1.1"},{"binary_name":"libfreerdp3-3","binary_version":"3.5.1+dfsg1-0ubuntu1.1"},{"binary_name":"libwinpr-tools3-3","binary_version":"3.5.1+dfsg1-0ubuntu1.1"},{"binary_name":"libwinpr3-3","binary_version":"3.5.1+dfsg1-0ubuntu1.1"},{"binary_name":"winpr3-utils","binary_version":"3.5.1+dfsg1-0ubuntu1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-4478.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
