{"id":"USN-6885-2","summary":"apache2 regression","details":"USN-6885-1 fixed vulnerabilities in Apache HTTP Server. One of the security\nfixes introduced a regression when proxying requests to a HTTP/2 server.\nThis update fixes the problem.\n\nWe apologize for the inconvenience.\n\nOriginal advisory details:\n\n Marc Stern discovered that the Apache HTTP Server incorrectly handled\n serving WebSocket protocol upgrades over HTTP/2 connections. A remote\n attacker could possibly use this issue to cause the server to crash,\n resulting in a denial of service. (CVE-2024-36387)\n \n Orange Tsai discovered that the Apache HTTP Server mod_proxy module\n incorrectly sent certain request URLs with incorrect encodings to backends.\n A remote attacker could possibly use this issue to bypass authentication.\n (CVE-2024-38473)\n \n Orange Tsai discovered that the Apache HTTP Server mod_rewrite module\n incorrectly handled certain substitutions. A remote attacker could possibly\n use this issue to execute scripts in directories not directly reachable\n by any URL, or cause a denial of service. Some environments may require\n using the new UnsafeAllow3F flag to handle unsafe substitutions.\n (CVE-2024-38474, CVE-2024-38475, CVE-2024-39573)\n \n Orange Tsai discovered that the Apache HTTP Server incorrectly handled\n certain response headers. A remote attacker could possibly use this issue\n to obtain sensitive information, execute local scripts, or perform SSRF\n attacks. (CVE-2024-38476)\n \n Orange Tsai discovered that the Apache HTTP Server mod_proxy module\n incorrectly handled certain requests. A remote attacker could possibly use\n this issue to cause the server to crash, resulting in a denial of service.\n (CVE-2024-38477)\n \n It was discovered that the Apache HTTP Server incorrectly handled certain\n handlers configured via AddType. A remote attacker could possibly use this\n issue to obtain source code.
