Alpine: multiple icinga2 packages: security update to 2.13.1-r0

high Tenable Self-Hosted Container Security Plugin ID 426182

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Icinga is a monitoring system which checks the availability of network resources, notifies users of
outages, and generates performance data for reporting. In versions 2.5.0 through 2.13.0,
ElasticsearchWriter, GelfWriter, InfluxdbWriter and Influxdb2Writer do not verify the server's certificate
despite a certificate authority being specified. Icinga 2 instances which connect to any of the mentioned
time series databases (TSDBs) using TLS over a spoofable infrastructure should immediately upgrade to
version 2.13.1, 2.12.6, or 2.11.11 to patch the issue. Such instances should also change the credentials
(if any) used by the TSDB writer feature to authenticate against the TSDB. There are no workarounds aside
from upgrading. (CVE-2021-37698)
