Alpine: apache2: security update to 2.4.27-r1

high Tenable Self-Hosted Container Security Plugin ID 403537

Description

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

 - Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be
 set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This
 affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an
 unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue
 and thus secret data is not always sent, and the specific data depends on many factors including
 configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in
 server/core.c. (CVE-2017-9798)
