Alpine: multiple bind packages: security update to 9.16.27-r0

medium Tenable Self-Hosted Container Security Plugin ID 423715

Description

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

- In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 -> 9.11.35-S1 and 9.16.8-S1 ->
9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.18 of the BIND
9.17 development branch, exploitation of broken authoritative servers using a flaw in response processing
can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it
possible for its internal data structures to grow almost infinitely, which may cause significant delays in
client query processing. (CVE-2021-25219)

- BIND 9.11.0 -> 9.11.36 9.12.0 -> 9.16.26 9.17.0 -> 9.18.0 BIND Supported Preview Editions: 9.11.4-S1 ->
9.11.36-S1 9.16.8-S1 -> 9.16.26-S1 Versions of BIND 9 earlier than those shown - back to 9.1.0, including
Supported Preview Editions - are also believed to be affected but have not been tested as they are EOL.
The cache could become poisoned with incorrect records leading to queries being made to the wrong servers,
which might also result in false information being returned to clients. (CVE-2021-25220)

- BIND 9.16.11 -> 9.16.26, 9.17.0 -> 9.18.0 and versions 9.16.11-S1 -> 9.16.26-S1 of the BIND Supported
Preview Edition. Specifically crafted TCP streams can cause connections to BIND to remain in CLOSE_WAIT
status for an indefinite period of time, even after the client has terminated the connection.
(CVE-2022-0396)
