Amazon Linux 2023: CVE-2024-43204: Important priority package update for httpd

SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a URL controlled by the attacker.  Requires an unlikely configuration where mod_headers is configured to modify the Content-Type request or response header with a value provided in the HTTP request.
Users are recommended to upgrade to version 2.4.64 which fixes this issue.
A Server-side request forgery (SSRF) vulnerability exists in Apache httpd when the server has mod_proxy loaded and is configured with mod_headers to modify the Content-Type header in the HTTP request or response using a value supplied by the user. Under this configuration, this flaw allows an attacker to craft specially crafted requests to manipulate the Content-Type header and trigger outbound requests to arbitrary attacker-controlled URLs via proxy. The vulnerability stems from inadequate input validation and unsafe header manipulation, ultimately allowing an attacker to influence server-side network behavior.
