Original advisory details:

 Orange Tsai discovered that the Apache HTTP Server mod_rewrite module
 incorrectly handled certain substitutions. A remote attacker could
 possibly use this issue to execute scripts in directories not directly
 reachable by any URL, or cause a denial of service. Some environments
 may require using the new UnsafeAllow3F flag to handle unsafe
 substitutions. (CVE-2024-38474, CVE-2024-38475)

 Orange Tsai discovered that the Apache HTTP Server incorrectly handled
 certain response headers. A remote attacker could possibly use this issue
 to obtain sensitive information, execute local scripts, or perform SSRF
 attacks. (CVE-2024-38476)

 Orange Tsai discovered that the Apache HTTP Server mod_proxy module
 incorrectly handled certain requests. A remote attacker could possibly use
 this issue to cause the server to crash, resulting in a denial of service.
 (CVE-2024-38477)");
