Description

apache2 regression USN-6885-1 fixed a vulnerability in Apache. The patch for CVE-2024-38474 was incomplete and caused regressions. This update provides the fix for that issue. 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)
