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 : - A flaw was found in the implementation of NFS v4.1 in the Linux kernel. NFS v4.1 shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel ID and cause a use-after-free. A malicious user in a container can exploit this to cause a host kernel memory corruption and a system crash. 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.
