Alpine: bind: security update to 9.16.4-r0

medium Tenable Self-Hosted Container Security Plugin ID 403668

Description

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

- An attacker who is permitted to send zone data to a server via zone transfer can exploit this to
intentionally trigger the assertion failure with a specially constructed zone, denying service to clients.
(CVE-2020-8618)

- In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND
Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service
for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk
("*") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone
content could theoretically introduce such a record in order to exploit this condition to cause denial of
service, though we consider the use of this vector unlikely because any such attack would require a
significant privilege level and be easily traceable. (CVE-2020-8619)
