Package : modsecurity-apache CVE ID : CVE-2025-47947 CVE-2025-48866 Debian Bug : 1106286 1107196

Several vulnerabilities were discovered in modsecurity-apache, an Apache module to tighten the Web application security, which may result in denial of service (high memory consumption).

For the stable distribution (bookworm), these problems have been fixed in version 2.9.7-1+deb12u1.

We recommend that you upgrade your modsecurity-apache packages.
