The remote Virtuozzo host is missing a security update.
According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerability : - [3.10.0-693.17.1.vz7.43.10 to 3.10.0-957.12.2.vz7.96.21] vhost-net: guest to host kernel escape during migration. A buffer overflow vulnerability was found in the networking virtualization functionality (vhost-net) that could be abused during live migration of virtual machines. A privileged guest user may pass descriptors with invalid length to the host when live migration is underway to crash the host kernel or, potentially, escalate their privileges on the host. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
