{"id":"ALPINE-CVE-2020-12430","details":"An issue was discovered in qemuDomainGetStatsIOThread in qemu/qemu_driver.c in libvirt 4.10.0 though 6.x before 6.1.0. A memory leak was found in the virDomainListGetStats libvirt API that is responsible for retrieving domain statistics when managing QEMU guests. This flaw allows unprivileged users with a read-only connection to cause a memory leak in the domstats command, resulting in a potential denial of service.","modified":"2025-11-19T06:17:09.022953Z","published":"2020-04-28T20:15:12.717Z","upstream":["CVE-2020-12430"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-12430"}],"affected":[{"package":{"name":"libvirt","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/libvirt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.5.0-r1"}]}],"versions":["0.10.0-r0","0.10.1-r0","0.10.1-r1","0.10.2-r0","0.10.2-r1","0.10.2-r2","0.10.2-r3","0.10.2-r4","0.10.2-r5","0.8.4-r0","0.8.4-r1","0.8.5-r0","0.8.6-r0","0.8.6-r1","0.8.6-r2","0.8.7-r0","0.8.8-r0","0.9.0-r0","0.9.1-r0","0.9.1-r1","0.9.1-r2","0.9.10-r0","0.9.10-r1","0.9.10-r2","0.9.10-r3","0.9.11-r0","0.9.12-r0","0.9.12-r1","0.9.12-r2","0.9.12-r3","0.9.13-r0","0.9.2-r0","0.9.2-r1","0.9.2-r2","0.9.2-r3","0.9.3-r0","0.9.3-r1","0.9.4-r0","0.9.4-r1","0.9.6-r0","0.9.6-r1","0.9.9-r0","1.0.2-r0","1.0.2-r1","1.0.3-r0","1.0.4-r0","1.0.5-r0","1.0.5-r1","1.0.6-r0","1.0.6-r1","1.0.6-r2","1.1.0-r0","1.1.0-r1","1.1.0-r2","1.1.1-r0","1.1.1-r1","1.1.2-r0","1.1.2-r1","1.1.3-r0","1.1.4-r0","1.2.0-r0","1.2.0-r1","1.2.0-r2","1.2.0-r3","1.2.0-r4","1.2.1-r0","1.2.10-r0","1.2.10-r1","1.2.11-r0","1.2.12-r0","1.2.13-r0","1.2.13-r1","1.2.14-r0","1.2.14-r1","1.2.14-r2","1.2.15-r0","1.2.15-r1","1.2.16-r0","1.2.17-r0","1.2.17-r1","1.2.17-r2","1.2.18-r0","1.2.18-r1","1.2.19-r0","1.2.2-r0","1.2.20-r0","1.2.20-r1","1.2.21-r0","1.2.21-r1","1.2.21-r2","1.2.3-r0","1.2.3-r1","1.2.3-r2","1.2.3-r3","1.2.4-r0","1.2.5-r0","1.2.6-r0","1.2.6-r1","1.2.7-r0","1.2.7-r1","1.2.8-r0","1.2.9-r0","1.2.9-r1","1.3.1-r0","1.3.2-r0","1.3.3-r0","1.3.3-r1","1.3.3-r2","1.3.5-r0","1.3.5-r1","1.3.5-r2","2.0.0-r0","2.1.0-r0","2.2.0-r0","2.3.0-r0","2.3.0-r1","2.5.0-r1","3.0.0-r0","3.1.0-r0","3.10.0-r0","3.2.0-r0","3.2.0-r1","3.2.0-r2","3.3.0-r0","3.3.0-r1","3.4.0-r0","3.4.0-r1","3.5.0-r0","3.6.0-r0","3.7.0-r0","3.8.0-r0","3.9.0-r0","3.9.0-r1","4.0.0-r0","4.1.0-r0","4.10.0-r0","4.10.0-r1","4.2.0-r0","4.3.0-r0","4.4.0-r0","4.5.0-r0","4.6.0-r0","4.6.0-r1","5.0.0-r0","5.0.0-r1","5.1.0-r0","5.2.0-r0","5.3.0-r0","5.3.0-r1","5.3.0-r2","5.4.0-r0","5.5.0-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12430.json"}},{"package":{"name":"libvirt","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/libvirt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.9.0-r1"}]}],"versions":["0.10.0-r0","0.10.1-r0","0.10.1-r1","0.10.2-r0","0.10.2-r1","0.10.2-r2","0.10.2-r3","0.10.2-r4","0.10.2-r5","0.8.4-r0","0.8.4-r1","0.8.5-r0","0.8.6-r0","0.8.6-r1","0.8.6-r2","0.8.7-r0","0.8.8-r0","0.9.0-r0","0.9.1-r0","0.9.1-r1","0.9.1-r2","0.9.10-r0","0.9.10-r1","0.9.10-r2","0.9.10-r3","0.9.11-r0","0.9.12-r0","0.9.12-r1","0.9.12-r2","0.9.12-r3","0.9.13-r0","0.9.2-r0","0.9.2-r1","0.9.2-r2","0.9.2-r3","0.9.3-r0","0.9.3-r1","0.9.4-r0","0.9.4-r1","0.9.6-r0","0.9.6-r1","0.9.9-r0","1.0.2-r0","1.0.2-r1","1.0.3-r0","1.0.4-r0","1.0.5-r0","1.0.5-r1","1.0.6-r0","1.0.6-r1","1.0.6-r2","1.1.0-r0","1.1.0-r1","1.1.0-r2","1.1.1-r0","1.1.1-r1","1.1.2-r0","1.1.2-r1","1.1.3-r0","1.1.4-r0","1.2.0-r0","1.2.0-r1","1.2.0-r2","1.2.0-r3","1.2.0-r4","1.2.1-r0","1.2.10-r0","1.2.10-r1","1.2.11-r0","1.2.12-r0","1.2.13-r0","1.2.13-r1","1.2.14-r0","1.2.14-r1","1.2.14-r2","1.2.15-r0","1.2.15-r1","1.2.16-r0","1.2.17-r0","1.2.17-r1","1.2.17-r2","1.2.18-r0","1.2.18-r1","1.2.19-r0","1.2.2-r0","1.2.20-r0","1.2.20-r1","1.2.21-r0","1.2.21-r1","1.2.21-r2","1.2.3-r0","1.2.3-r1","1.2.3-r2","1.2.3-r3","1.2.4-r0","1.2.5-r0","1.2.6-r0","1.2.6-r1","1.2.7-r0","1.2.7-r1","1.2.8-r0","1.2.9-r0","1.2.9-r1","1.3.1-r0","1.3.2-r0","1.3.3-r0","1.3.3-r1","1.3.3-r2","1.3.5-r0","1.3.5-r1","1.3.5-r2","2.0.0-r0","2.1.0-r0","2.2.0-r0","2.3.0-r0","2.3.0-r1","2.5.0-r1","3.0.0-r0","3.1.0-r0","3.10.0-r0","3.2.0-r0","3.2.0-r1","3.2.0-r2","3.3.0-r0","3.3.0-r1","3.4.0-r0","3.4.0-r1","3.5.0-r0","3.6.0-r0","3.7.0-r0","3.8.0-r0","3.9.0-r0","3.9.0-r1","4.0.0-r0","4.1.0-r0","4.10.0-r0","4.10.0-r1","4.2.0-r0","4.3.0-r0","4.4.0-r0","4.5.0-r0","4.6.0-r0","4.6.0-r1","5.0.0-r0","5.0.0-r1","5.1.0-r0","5.2.0-r0","5.3.0-r0","5.3.0-r1","5.3.0-r2","5.4.0-r0","5.5.0-r0","5.6.0-r0","5.7.0-r0","5.8.0-r0","5.9.0-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-12430.json"}},{"package":{"name":"libvirt","ecosystem":"Alpine:v3.8","purl":"pkg:apk/alpine/libvirt?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.5.0-r1"}]}],"versions":["0.10.0-r0","0.10.1-r0","0.10.1-r1","0.10.2-r0","0.10.2-r1","0.10.2-r2","0.10.2-r3","0.10.2-r4","0.10.2-r5","0.8.4-r0","0.8.4-r1","0.8.5-r0","0.8.6-r0","0.8.6-r1","0.8.6-r2","0.8.7-r0","0.8.8-r0","0.9.0-r0","0.9.1-r0","0.9.1-r1","0.9.1-r2","0.9.10-r0","0.9.10-r1","0.9.10-r2","0.9.10-r3","0.9.11-r0","0.9.12-r0","0.9.12-r1","0.9.12-r2","0.9.12-r3","0.9.13-r0","0.9.2-r0","0.9.2-r1","0.9.2-r2","0.9.2-r3","0.9.3-r0","0.9.3
