Alpine: multiple apache2 packages: security update to 2.4.23-r0 (deprecated)

high Tenable Self-Hosted Container Security Plugin ID 400963

Description

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

- The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect
applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which
might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy
server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states
"This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for
a vulnerability. (CVE-2016-5387)
