{"id":"DEBIAN-CVE-2026-61477","details":"An injection vulnerability was found in libvirt's virtual network driver. The network XML parser does not strip newline characters from DNS TXT record value attributes and SRV record domain/target attributes. These values are written verbatim into the dnsmasq configuration file generated by the network driver, allowing a user with permission to define virtual networks to inject arbitrary dnsmasq configuration directives such as dhcp-script, leading to arbitrary command execution as root.","modified":"2026-09-12T10:00:27.951582248Z","published":"2026-08-07T14:17:00.187Z","upstream":["CVE-2026-61477"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-61477"}],"affected":[{"package":{"name":"libvirt","ecosystem":"Debian:12","purl":"pkg:deb/debian/libvirt?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.0.0-1","10.0.0-2","10.0.0-3","10.1.0-1","10.10.0-1","10.10.0-2","10.10.0-3","10.10.0-4","10.2.0-1","10.3.0-1","10.3.0-2","10.3.0-3","10.4.0-1","10.5.0-1","10.6.0-1","10.6.0-2","10.6.0-3","10.7.0-1","10.7.0-2","10.7.0-3","10.8.0-1","10.9.0-1","10.9.0-2","11.0.0-1","11.0.0-2","11.1.0-1","11.1.0-2","11.10.0-1","11.10.0-2","11.2.0-1","11.2.0-2","11.2.0-3","11.3.0-1","11.3.0-2","11.3.0-2~bpo12+1","11.3.0-3","11.4.0-1","11.5.0-1","11.6.0-1","11.7.0-1","11.8.0-1","11.8.0-2","11.9.0-1","11.9.0-2","12.0.0-1","12.1.0-1","12.2.0-1","12.3.0-1","12.4.0-1","12.5.0-1","12.6.0-1","12.7.0-1","9.0.0-4","9.0.0-4+deb12u1","9.0.0-4+deb12u2","9.1.0-1","9.10.0-1","9.2.0-1","9.2.0-2","9.3.0-1","9.3.0-2","9.4.0-1","9.5.0-1","9.5.0-2","9.6.0-1","9.6.0-2","9.6.0-3","9.7.0-1","9.8.0-1","9.8.0-2","9.9.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-61477.json"}},{"package":{"name":"libvirt","ecosystem":"Debian:13","purl":"pkg:deb/debian/libvirt?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"11.3.0-3+deb13u3"}]}],"versions":["11.3.0-3","11.3.0-3+deb13u1","11.3.0-3+deb13u2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-61477.json"}},{"package":{"name":"libvirt","ecosystem":"Debian:14","purl":"pkg:deb/debian/libvirt?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"12.6.0-1"}]}],"versions":["11.10.0-1","11.10.0-2","11.3.0-3","11.4.0-1","11.5.0-1","11.6.0-1","11.7.0-1","11.8.0-1","11.8.0-2","11.9.0-1","11.9.0-2","12.0.0-1","12.1.0-1","12.2.0-1","12.3.0-1","12.4.0-1","12.5.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-61477.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N"}]}
