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 10 buster, these problems have been fixed in version 1:9.11.5.P4+dfsg-5.1+deb10u14.
For Debian 9 stretch, these problems have been fixed in version 1:9.10.3.dfsg.P4-12.3+deb9u18.
We recommend that you upgrade your bind9 packages.
