EulerOS Virtualization 2.5.0 : dhcp (EulerOS-SA-2018-1250)

high Nessus Plugin ID 117559

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the dhcp packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - An out-of-bound memory access flaw was found in the way dhclient processed a DHCP response packet. A malicious DHCP server could potentially use this flaw to crash dhclient processes running on DHCP client machines via a crafted DHCP response packet.(CVE-2018-5732)

 - A denial of service flaw was found in the way dhcpd handled reference counting when processing client requests. A malicious DHCP client could use this flaw to trigger a reference count overflow on the server side, potentially causing dhcpd to crash, by sending large amounts of traffic.(CVE-2018-5733)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected dhcp packages.
