Alpine: bind: security update to 9.18.19-r0

high Tenable Self-Hosted Container Security Plugin ID 403673

Description

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

 - The code that processes control channel messages sent to `named` calls certain functions recursively
 during packet parsing. Recursion depth is only limited by the maximum accepted packet size; depending on
 the environment, this may cause the packet-parsing code to run out of available stack memory, causing
 `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its
 contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key;
 only network access to the control channel's configured TCP port is necessary. This issue affects BIND 9
 versions 9.2.0 through 9.16.43, 9.18.0 through 9.18.18, 9.19.0 through 9.19.16, 9.9.3-S1 through
 9.16.43-S1, and 9.18.0-S1 through 9.18.18-S1. (CVE-2023-3341)

 - A flaw in the networking code handling DNS-over-TLS queries may cause `named` to terminate unexpectedly
 due to an assertion failure. This happens when internal data structures are incorrectly reused under
 significant DNS-over-TLS query load. This issue affects BIND 9 versions 9.18.0 through 9.18.18 and
 9.18.11-S1 through 9.18.18-S1. (CVE-2023-4236)
