The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:1469 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: An assertion check can fail while answering queries for DNAME records that require the DNAME to be     processed to resolve itself (CVE-2021-25215)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

  - In BIND 9.8.5 -> 9.8.8, 9.9.3 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and     9.16.8-S1 -> 9.16.13-S1 of BIND 9 Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11     of the BIND 9.17 development branch, when a vulnerable version of named receives a malformed IXFR     triggering the flaw described above, the named process will terminate due to a failed assertion the next     time the transferred secondary zone is refreshed. (CVE-2021-25214)

  - In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 ->     9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND     9.17 development branch, when a vulnerable version of named receives a query for a record triggering the     flaw described above, the named process will terminate due to a failed assertion check. The vulnerability     affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other     versions of BIND 9. (CVE-2021-25215)

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

This update for bind fixes the following issues :

CVE-2021-25214: Fixed a broken inbound incremental zone update (IXFR) which could have caused named to terminate unexpectedly (bsc#1185345).

CVE-2021-25215: Fixed an assertion check which could have failed while answering queries for DNAME records that required the DNAME to be processed to resolve itself (bsc#1185345).

Switched from /var/run to /run (bsc#1185073)

Hardening: Compiled binary with PIE flags to make it position independent

The version of AOS installed on the remote host is prior to 6.0. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.0 advisory.

  - encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write     access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character     sequence. (CVE-2021-26937)

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5715)

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis     of the data cache. (CVE-2017-5754)

  - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java     SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16;
    Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks require human     interaction from a person other than the attacker. Successful attacks of this vulnerability can result in     unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded,     Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments     that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox     for security. (CVE-2021-2163)

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

The version of AOS installed on the remote host is prior to 6.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.1 advisory.

  - xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and     watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows     remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory     corruption) via a crafted XML document. (CVE-2016-4658)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)
