- CVEs with nessus.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 :
- It was discovered that nfnl_cthelper_list structure was
accessible to any user with CAP_NET_ADMIN capability in
a network namespace. An unprivileged local user could
exploit that to affect netfilter conntrack helpers on
the host.
- It was discovered that a nlmon link inside a child
network namespace was not restricted to that namespace.
An unprivileged local user could exploit that to
monitor system-wide netlink activity.
- It was discovered that xt_osf_fingers data structure
was accessible from any network namespace. This allowed
unprivileged local users to bypass intended access
restrictions and modify the system-wide OS fingerprint
list used by specific iptables rules.
- The KEYS subsystem omitted an access-control check when
writing a key to the default keyring of the current
task, allowing a local user to bypass security checks
for the keyring. This compromised the validity of the
keyring for those who relied on it.
- If 'dccp_ipv6' module was loaded on the host, a local
unprivileged user could trigger a kernel crash in
dccp_write_xmit() or inet_csk_get_port() using 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.
