Virtuozzo 7 : readykernel-patch (VZA-2019-004)

Medium Nessus Plugin ID 121420

Synopsis

The remote Virtuozzo host is missing a security update.

Description

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 vulnerabilities :

- A flaw was found in the implementation of ebtables in the Linux kernel. A local attacker in a container could exploit it to consume large amounts of memory, eventually causing denial of service on the host.

- vhost: kernel crash (access out of bounds) in memcpy_fromiovecend().

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.

Solution

Update the readykernel patch.
