Alpine: multiple bind packages: security update to 9.12.1_p2-r0

high Tenable Cloud Security Plugin ID 423736

Description

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

- An error in zone database reference counting can lead to an assertion failure if a server which is running
an affected version of BIND attempts several transfers of a slave zone in quick succession. This defect
could be deliberately exercised by an attacker who is permitted to cause a vulnerable server to initiate
zone transfers (for example: by sending valid NOTIFY messages), causing the named process to exit after
failing the assertion test. Affects BIND 9.12.0 and 9.12.1. (CVE-2018-5736)

- A problem with the implementation of the new serve-stale feature in BIND 9.12 can lead to an assertion
failure in rbtdb.c, even when stale-answer-enable is off. Additionally, problematic interaction between
the serve-stale feature and NSEC aggressive negative caching can in some cases cause undesirable behavior
from named, such as a recursion loop or excessive logging. Deliberate exploitation of this condition could
cause operational problems depending on the particular manifestation -- either degradation or denial of
service. Affects BIND 9.12.0 and 9.12.1. (CVE-2018-5737)
