Test ID:1.3.6.1.4.1.25623.1.1.2.2021.2354
Category:Huawei EulerOS Local Security Checks
Title:Huawei EulerOS: Security Advisory for bind (EulerOS-SA-2021-2354)
Summary:The remote host is missing an update for the Huawei EulerOS 'bind' package(s) announced via the EulerOS-SA-2021-2354 advisory.
Description:Summary:
The remote host is missing an update for the Huawei EulerOS 'bind' package(s) announced via the EulerOS-SA-2021-2354 advisory.

Vulnerability Insight:
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.(CVE-2020-8625)

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.(CVE-2021-25215)

Affected Software/OS:
'bind' package(s) on Huawei EulerOS V2.0SP2.

Solution:
Please install the updated package(s).
