Virtuozzo 6 : parallels-server-bm-release / vzkernel / etc (VZA-2017-114)

High Nessus Plugin ID 105324

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 :

- dccp_disconnect() set the socket state to DCCP_CLOSED but did not properly free some of the resources associated with that socket. This could result in a use-after-free and could potentially allow an attacker to escalate their privileges.

- The Linux kernel is vulnerable to a use-after-free issue. It could occur while closing a xfrm netlink socket, in xfrm_dump_policy_done. A user/process could use this flaw to potentially escalate their privileges on a system.

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 affected parallels-server-bm-release / vzkernel / etc packages.
