Alpine: dovecot: security update to 2.3.19.1-r5

high Tenable Self-Hosted Container Security Plugin ID 404171

Description

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

 - An issue was discovered in the auth component in Dovecot 2.2 and 2.3 before 2.3.20. When two passdb
 configuration entries exist with the same driver and args settings, incorrect username_filter and
 mechanism settings can be applied to passdb definitions. These incorrectly applied settings can lead to an
 unintended security configuration and can permit privilege escalation in certain configurations. The
 documentation does not advise against the use of passdb definitions that have the same driver and args
 settings. One such configuration would be where an administrator wishes to use the same PAM configuration
 or passwd file for both normal and master users but use the username_filter setting to restrict which of
 the users is able to be a master user. (CVE-2022-30550)
