Package : bind9 CVE ID : CVE-2024-0760 CVE-2024-1737 CVE-2024-1975 CVE-2024-4076

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.
Details can be found at:
https://kb.isc.org/docs/rrset-limits-in-zones

For the oldstable distribution (bullseye), these problems have been fixed in version 1:9.16.50-1~deb11u1. For the oldstable distribution (bullseye) the limits to mitigate CVE-2024-1737 are hardcoded and not configurable.

For the stable distribution (bookworm), these problems have been fixed in version 1:9.18.28-1~deb12u1.

We recommend that you upgrade your bind9 packages.
