Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

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 :

- Change #4777 (introduced in October 2017) introduced an unforeseen issue in releases which were issued after that date, affecting which clients are permitted to make recursive queries to a BIND nameserver. The intended (and documented) behavior is that if an operator has not specified a value for the 'allow-recursion' setting, it SHOULD default to one of the following: none, if 'recursion no' is set in named.conf a value inherited from the 'allow-query-cache' or 'allow-query' settings IF 'recursion yes' (the default for that setting) AND match lists are explicitly set for 'allow-query-cache' or 'allow-query' (see the BIND9 Administrative Reference Manual section 6.2 for more details) or the intended default of 'allow-recursion {localhost localnets}' if 'recursion yes' is in effect and no values are explicitly set for 'allow-query-cache' or 'allow-query'. However, because of the regression introduced by change #4777, it is possible when 'recursion yes' is in effect and no match list values are provided for 'allow-query-cache' or 'allow-query' for the setting of 'allow-recursion' to inherit a setting of all hosts from the 'allow-query' setting default, improperly permitting recursion to all clients. Affects BIND 9.9.12, 9.10.7, 9.11.3, 9.12.0->9.12.1-P2, the development release 9.13.0, and also releases 9.9.12-S1, 9.10.7-S1, 9.11.3-S1, and 9.11.3-S2 from BIND 9 Supported Preview Edition.(CVE-2018-5738)

- 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-2019-6465)

- '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)

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.

Solution

Update the affected bind packages.
