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 the implementation of ebtables in the kernel did not properly validate the offsets received from the user space. A local user with enough privileges in the user and network namespaces could use that to trigger an out-of-bounds write to the kernel address space. 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.
