    * CVE-2024-38474: mod_rewrite: server weakness with encoded question marks in
    backreferences
    * CVE-2024-38475: mod_rewrite: server weakness in mod_rewrite when first segment
    of substitution matches filesystem path
    * CVE-2024-38477: mod_proxy: crash resulting in Denial of Service in mod_proxy
    via a malicious request
    * CVE-2024-38476: http: server use exploitable/malicious backend application
    output to run local handlers via internal redirect
    * CVE-2024-39573: mod_rewrite: proxy handler substitution
    CVE(s):
    CVE-2024-38474
    Substitution encoding issue in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows attacker to
    execute scripts in directories permitted by the configuration but not directly reachable by any URL or
    source disclosure of scripts meant to only to be executed as CGI. Users are recommended to upgrade to
    version 2.4.60, which fixes this issue. Some RewriteRules that capture and substitute unsafely will now
    fail unless rewrite flag UnsafeAllow3F is specified.
    CVE-2024-38475
    Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to
    map URLs to filesystem locations that are permitted to be served by the server but are not
    intentionally/directly reachable by any URL, resulting in code execution or source code disclosure.
    Substitutions in server context that use a backreferences or variables as the first segment of the
    substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag
    UnsafePrefixStat can be used to opt back in once ensuring the substitution is appropriately constrained.
    CVE-2024-38476
    Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerably to information disclosure,
    SSRF or local script execution via backend applications whose response headers are malicious or
    exploitable. Users are recommended to upgrade to version 2.4.60, which fixes this issue.
    CVE-2024-38477
    null pointer dereference in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows an attacker to crash
    the server via a malicious request. Users are recommended to upgrade to version 2.4.60, which fixes this
    issue.
    CVE-2024-39573
    Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe
    RewriteRules to unexpectedly setup URL's to be handled by mod_proxy. Users are recommended to upgrade to
    version 2.4.60, which fixes this issue.
