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 : - It was discovered that a race condition between packet_do_bind() and packet_notifier() in the implementation of AF_PACKET could lead to use-after-free. An unprivileged user on the host or in a container could exploit this to crash the kernel or, potentially, to escalate their privileges in the system. 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.
