Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges.","published":"2019-08-02T13:15:12.000Z","lastModified":"2026-06-17T02:10:24.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-250","CWE-284","CWE-22"],"affected":["redhat/libvirt","redhat/enterprise linux","redhat/enterprise linux desktop","redhat/enterprise linux server","redhat/enterprise linux server aus","redhat/enterprise linux server eus","redhat/enterprise linux server tus","redhat/enterprise linux workstation","redhat/virtualization"],"epss":{"score":0.00549,"percentile":0.45789,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.55%).
