 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4050-1 [email protected] https://www.debian.org/lts/security/ Paride Legovini February 11, 2025 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 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:
 https://security-tracker.debian.org/tracker/bind9

Solution

Upgrade the bind9 packages.
