Alpine: bind: security update to 9.11.6_p1-r0

high Tenable Self-Hosted Container Security Plugin ID 403645

Description

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

 - By design, BIND is intended to limit the number of TCP clients that can be connected at any given time.
 The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value
 for most servers. Unfortunately, the code which was intended to limit the number of simultaneous
 connections contained an error which could be exploited to grow the number of simultaneous connections
 beyond this limit. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.6, 9.12.0 -> 9.12.4, 9.14.0.
 BIND 9 Supported Preview Edition versions 9.9.3-S1 -> 9.11.5-S3, and 9.11.5-S5. Versions 9.13.0 -> 9.13.7
 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for
 vulnerability to CVE-2018-5743. (CVE-2018-5743)

 - A programming error in the nxdomain-redirect feature can cause an assertion failure in query.c if the
 alternate namespace used by nxdomain-redirect is a descendant of a zone that is served locally. The most
 likely scenario where this might occur is if the server, in addition to performing NXDOMAIN redirection
 for recursive clients, is also serving a local copy of the root zone or using mirroring to provide the
 root zone, although other configurations are also possible. Versions affected: BIND 9.12.0-> 9.12.4,
 9.14.0. Also affects all releases in the 9.13 development branch. (CVE-2019-6467)
