Virtuozzo 6 : parallels-server-bm-release / vzkernel / etc (VZA-2017-037)

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote Virtuozzo host is missing multiple security updates.

Description :

According to the versions of the parallels-server-bm-release /
vzkernel / etc packages installed, the Virtuozzo installation on the
remote host is affected by the following vulnerabilities :

- The NFSv2 and NFSv3 server implementations in the Linux
kernel through 4.10.13 lack certain checks for the end
of a buffer. A remote attacker could trigger a
pointer-arithmetic error or possibly have unspecified
other impact via crafted requests related to
fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.

- The NFSv2/NFSv3 server in the nfsd subsystem in the
Linux kernel through 4.10.11 allowed remote attackers
to cause a denial of service (system crash) via a long
RPC reply, related to net/sunrpc/svc.c,
fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c.

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.
