From Red Hat Security Advisory 2020:2338 :

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2338 advisory.

  - bind: BIND does not sufficiently limit the number of     fetches performed when processing referrals     (CVE-2020-8616)

  - bind: A logic error in code which checks TSIG validity     can be used to trigger an assertion failure in tsig.c     (CVE-2020-8617)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2020:2893 advisory.

  - bind: A logic error in code which checks TSIG validity can be used to trigger an assertion failure in     tsig.c (CVE-2020-8617)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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 :

  - Using a specially-crafted message, an attacker may     potentially cause a BIND server to reach an     inconsistent state if the attacker knows (or     successfully guesses) the name of a TSIG key used by     the server. Since BIND, by default, configures a local     session key even on servers whose configuration does     not otherwise make use of it, almost all current BIND     servers are vulnerable. In releases of BIND dating from     March 2018 and after, an assertion check in tsig.c     detects this inconsistent state and deliberately exits.
    Prior to the introduction of the check the server would     continue operating in an inconsistent state, with     potentially harmful results.(CVE-2020-8617)

  - A malicious actor who intentionally exploits this lack     of effective limitation on the number of fetches     performed when processing referrals can, through the     use of specially crafted referrals, cause a recursing     server to issue a very large number of fetches in an     attempt to process the referral. This has at least two     potential effects: The performance of the recursing     server can potentially be degraded by the additional     work required to perform these fetches, and The     attacker can 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.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3475 advisory.

    The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols.
    BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing     with DNS); and tools for verifying that the DNS server is operating correctly.

    Security Fix(es):

    * bind: BIND does not sufficiently limit the number of fetches performed when processing referrals     (CVE-2020-8616)

    * bind: A logic error in code which checks TSIG validity can be used to trigger an assertion failure in     tsig.c (CVE-2020-8617)

The remote NewStart CGSL host, running version MAIN 6.01, has bind packages installed that are affected by multiple vulnerabilities:

  - With pipelining enabled each incoming query on a TCP     connection requires a similar resource allocation to a     query received via UDP or via TCP without pipelining     enabled. A client using a TCP-pipelined connection to a     server could consume more resources than the server has     been provisioned to handle. When a TCP connection with a     large number of pipelined queries is closed, the load on     the server releasing these multiple resources can cause     it to become unresponsive, even for queries that can be     answered authoritatively or from cache. (This is most     likely to be perceived as an intermittent server     problem). (CVE-2019-6477)

  - A malicious actor who intentionally exploits this lack     of effective limitation on the number of fetches     performed when processing referrals can, through the use     of specially crafted referrals, cause a recursing server     to issue a very large number of fetches in an attempt to     process the referral. This has at least two potential     effects: The performance of the recursing server can     potentially be degraded by the additional work required     to perform these fetches, and The attacker can exploit     this behavior to use the recursing server as a reflector     in a reflection attack with a high amplification factor.
    (CVE-2020-8616)

  - Using a specially-crafted message, an attacker may     potentially cause a BIND server to reach an inconsistent     state if the attacker knows (or successfully guesses)     the name of a TSIG key used by the server. Since BIND,     by default, configures a local session key even on     servers whose configuration does not otherwise make use     of it, almost all current BIND servers are vulnerable.
    In releases of BIND dating from March 2018 and after, an     assertion check in tsig.c detects this inconsistent     state and deliberately exits. Prior to the introduction     of the check the server would continue operating in an     inconsistent state, with potentially harmful results.
