Virtuozzo 7 : readykernel-patch (VZA-2017-010)

high Nessus Plugin ID 97982

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 :

- The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel before 4.9.11 allows remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag.

- A privileged user inside a container could cause a host kernel crash in udp_lib_get_port().

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.
