CVE-2019-3886

MEDIUM
New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

An incorrect permissions check was discovered in libvirt 4.8.0 and above. The readonly permission was allowed to invoke APIs depending on the guest agent, which could lead to potentially disclosing unintended information or denial of service by causing libvirt to block.
