Alpine: multiple apache2 packages: security update to 2.4.27-r0 (deprecated)

high Tenable Cloud Security Plugin ID 400810

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)
