Name of the Vulnerable Software and Affected Versions libvirt versions 2.3.0 and later
Description The issue is related to errors in the certificate authentication procedure in the Libvirt virtualization management library. Exploitation of this issue allows a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The problem is caused by a bad default configuration where "verify-peer=no" is passed to QEMU by libvirt, resulting in a failure to validate SSL/TLS certificates by default.
Recommendations For libvirt versions 2.3.0 and later, change the default configuration to "verify-peer=yes" to ensure validation of SSL/TLS certificates.
