There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - By design, BIND is intended to limit the number of TCP clients that can be connected at any given time.
    The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value
    for most servers. Unfortunately, the code which was intended to limit the number of simultaneous
    connections contained an error which could be exploited to grow the number of simultaneous connections
    beyond this limit. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.6, 9.12.0 -> 9.12.4, 9.14.0.
    BIND 9 Supported Preview Edition versions 9.9.3-S1 -> 9.11.5-S3, and 9.11.5-S5. Versions 9.13.0 -> 9.13.7
    of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for
    vulnerability to CVE-2018-5743. (CVE-2018-5743)

  - A programming error in the nxdomain-redirect feature can cause an assertion failure in query.c if the
    alternate namespace used by nxdomain-redirect is a descendant of a zone that is served locally. The most
    likely scenario where this might occur is if the server, in addition to performing NXDOMAIN redirection
    for recursive clients, is also serving a local copy of the root zone or using mirroring to provide the
    root zone, although other configurations are also possible. Versions affected: BIND 9.12.0-> 9.12.4,
    9.14.0. Also affects all releases in the 9.13 development branch. (CVE-2019-6467)

ISC BIND versions 9.12.x prior to 9.12.4-P1, or 9.13.x prior to 9.14.1 are affected by a DoS vulnerability in the nxdomain-redirect feature in the query.c. An unauthenticated, remote attacker can exploit this issue, to cause the application to stop responding.

According to the versions of the bind packages installed, the EulerOS installation on the remote host is affected by the following 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 programming error in the nxdomain-redirect feature     can cause an assertion failure in query.c if the     alternate namespace used by nxdomain-redirect is a     descendant of a zone that is served locally. The most     likely scenario where this might occur is if the     server, in addition to performing NXDOMAIN redirection     for recursive clients, is also serving a local copy of     the root zone or using mirroring to provide the root     zone, although other configurations are also possible.
    Versions affected: BIND 9.12.0-> 9.12.4, 9.14.0. Also     affects all releases in the 9.13 development     branch.(CVE-2019-6467)

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.

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 :

  - A programming error in the nxdomain-redirect feature     can cause an assertion failure in query.c if the     alternate namespace used by nxdomain-redirect is a     descendant of a zone that is served locally.
