Virtuozzo 7 : readykernel-patch (VZA-2017-082)

Medium Nessus Plugin ID 103425

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 :

- An unprivileged user inside a container could cause a denial of service (kernel crash in user_read() function) using a specially crafted sequence of system calls.

- The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel through 4.13.2 allows local users to cause a denial of service (panic) by leveraging incorrect length validation.

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.
