Summary
apache2 regression
Details

USN-6885-1 fixed vulnerabilities in Apache. The patch for CVE-2024-38474 was incomplete and caused a regression. This update provides the fix for this 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)
