Several vulnerabilities were discovered in BIND, a DNS server
implementation, which may result in denial of service.
To mitigate CVE-2024-1737 two new configuration statements have been
added to allow operators of secondary servers and recursive resolvers to
set an upper bound on the growth of data in their zones or caches.

For the oldstable distribution (bullseye), these problems have been
fixed in version 1:9.16.50-1~deb11u1. For the oldstable distribution
