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

  - ISC BIND through 9.9.9-P1, 9.10.x through 9.10.4-P1,     and 9.11.x through 9.11.0b1 allows primary DNS servers     to cause a denial of service (secondary DNS server     crash) via a large AXFR response, and possibly allows     IXFR servers to cause a denial of service (IXFR client     crash) via a large IXFR response and allows remote     authenticated users to cause a denial of service     (primary DNS server crash) via a large UPDATE     message.(CVE-2016-6170)

  - It was found that the controls for zone transfer were     not properly applied to Dynamically Loadable Zones     (DLZs). An attacker acting as a DNS client could use     this flaw to request and receive a zone transfer of a     DLZ even when not permitted to do so by the     'allow-transfer' ACL.(CVE-2019-6465)

  - To provide fine-grained controls over the ability to     use Dynamic DNS (DDNS) to update records in a zone,     BIND 9 provides a feature called update-policy. Various     rules can be configured to limit the types of updates     that can be performed by a client, depending on the key     used when sending the update request. Unfortunately,     some rule types were not initially documented, and when     documentation for them was added to the Administrator     Reference Manual (ARM) in change #3112, the language     that was added to the ARM at that time incorrectly     described the behavior of two rule types,     krb5-subdomain and ms-subdomain. This incorrect     documentation could mislead operators into believing     that policies they had configured were more restrictive     than they actually were. This affects BIND versions     prior to BIND 9.11.5 and BIND 9.12.3.(CVE-2018-5741)

  - An assertion failure was found in the way bind     implemented the 'managed keys' feature. An attacker     could use this flaw to cause the named daemon to crash.
    This flaw is very difficult for an attacker to trigger     because it requires an operator to have BIND configured     to use a trust anchor managed by the     attacker.(CVE-2018-5745)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0025 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-6465:
    Controls for zone transfers may not be properly applied to Dynamically Loadable Zones (DLZs) if the zones     are writable Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P2, 9.12.0 -> 9.12.3-P2, and     versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13     development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for     vulnerability to CVE-2019-6465.

    CVE-2019-6471:
    A race condition which may occur when discarding malformed packets can result in BIND exiting due to a     REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1,     9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND     9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1.

    CVE-2020-8617:
    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-2020-8622:
    In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the     BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating     the server receiving the TSIG-signed request, could send a truncated response to that request, triggering     an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to     correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and     message, and spoof a truncated response to trigger an assertion failure, causing the server to exit.

    CVE-2020-8623:
    In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the     BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted     query packet can trigger a crash. To be vulnerable, the system must: * be running BIND that was built with
    --enable-native-pkcs11 * be signing one or more zones with an RSA key * be able to receive queries from     a possible attacker

    CVE-2020-8624:
    In BIND 9.9.12 -> 9.9.13, 9.10.7 -> 9.10.8, 9.11.3 -> 9.11.21, 9.12.1 -> 9.16.5, 9.17.0 -> 9.17.3, also     affects 9.9.12-S1 -> 9.9.13-S1, 9.11.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An     attacker who has been granted privileges to change a specific subset of the zone's content could abuse     these unintended additional privileges to update other contents of the zone.

    CVE-2020-8625:
    BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG     features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed,     but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or     tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-     TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server     environments that combine BIND servers with Active Directory domain controllers. The most likely outcome     of a successful exploitation of the vulnerability is a crash of the named process. However, remote code     execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11,     and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.
    Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch

The version of AOS installed on the remote host is prior to 5.18. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.18 advisory.

  - When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to     Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP     connection. If such connections are available to an attacker, they can be exploited in ways that may be     surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped     with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected     (and recommended in the security guide) that this Connector would be disabled if not required. This     vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the     web application - processing any file in the web application as a JSP Further, if the web application     allowed file upload and stored those files within the web application (or the attacker was able to control     the content of the web application by some other means) then this, along with the ability to process a     file as a JSP, made remote code execution possible. It is important to note that mitigation is only     required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth     approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to     Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP     Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading     to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations.
    (CVE-2020-1938)

  - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a     certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)

  - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-     free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where,     the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error     occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by     the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction     mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism     to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that     host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.
    (CVE-2019-19338)

  - The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which     allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.
    (CVE-2015-8035)

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

  - 'managed-keys' is a feature which allows a BIND     resolver to automatically maintain the keys used by     trust anchors which operators configure for use in     DNSSEC validation. Due to an error in the managed-keys     feature it is possible for a BIND server which uses     managed-keys to exit due to an assertion failure if,     during key rollover, a trust anchor's keys are replaced     with keys which use an unsupported algorithm. Versions     affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P1,     9.12.0 -> 9.12.3-P1, and versions 9.9.3-S1 -> 9.11.5-S3     of BIND 9 Supported Preview Edition. Versions 9.13.0 ->     9.13.6 of the 9.13 development branch are also     affected. Versions prior to BIND 9.9.0 have not been     evaluated for vulnerability to     CVE-2018-5745.(CVE-2018-5745)
