    Package        : bind9     Version        : 1:9.16.50-1~deb11u3     CVE ID         : CVE-2024-11187

    One vulnerability was discovered in BIND, a DNS server implementation, which     may result in denial of service.

    It is possible to construct a zone such that some queries to it will generate     responses containing numerous records in the Additional section. An attacker     sending many such queries can cause either the authoritative server itself or     an independent resolver to use disproportionate resources processing the     queries. Zones will usually need to have been deliberately crafted to exploit     this flaw.

    For Debian 11 bullseye, this problem has been fixed in version     1:9.16.50-1~deb11u3.

    We recommend that you upgrade your bind9 packages.

    For the detailed security status of bind9 please refer to     its security tracker page at:
