EulerOS Virtualization for ARM 64 3.0.2.0 : bind (EulerOS-SA-2020-1953)

high Nessus Plugin ID 140323

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the bind packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

- An assertion failure was found in BIND, which checks the validity of messages containing TSIG resource records. This flaw allows an attacker that knows or successfully guesses the name of the TSIG key used by the server to use a specially-crafted message, potentially causing a BIND server to reach an inconsistent state or cause a denial of service. A majority of BIND servers have an internally-generated TSIG session key whose name is trivially guessable, and that key exposes the vulnerability unless specifically disabled.(CVE-2020-8617)

- A flaw was found in BIND, where it does not sufficiently limit the number of fetches that can be performed while processing a referral response. This flaw allows an attacker to cause a denial of service attack. The attacker can also exploit this behavior to use the recursing server as a reflector in a reflection attack with a high amplification factor.(CVE-2020-8616)

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 bind packages.
