EulerOS Virtualization 3.0.2.2 : dnsmasq (EulerOS-SA-2020-2215)

high Nessus Plugin ID 141645

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 - A vulnerability was found in dnsmasq before version 2.81, where the memory leak allows remote attackers to cause a denial of service (memory consumption) via vectors involving DHCP response creation.(CVE-2019-14834)

 - A vulnerability was found in Dnsmasq's implementation of DNSSEC. Wildcard synthesized NSEC records could be improperly interpreted to prove the non-existence of hostnames that actually exist.(CVE-2017-15107)

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 dnsmasq packages.
