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 vulnerabilities :
- A vulnerability was found in the Linux kernel where
having malicious IP options present would cause the
ipv4_pktinfo_prepare() function to drop/free the dst.
This could result in a system crash or possible
- A vulnerability was found in the implementation of SCTP
protocol in the Linux kernel. If the sctp module was
loaded on the host, a privileged user inside a
container could cause a kernel crash by triggering
use-after-free in the __sctp_connect() function with a
specially crafted sequence of system calls.
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.
