Debian: DSA-5851-1 Critical: pdns-recursor Denial of Service Risk

Toshifumi Sakaguchi discovered that too permissive parsing of some
resource record sets in the zone file parsing of PDNS Recursor could
result in denial of service.

For the stable distribution (bookworm), this problem has been fixed in
version 4.8.8-1+deb12u1.

We recommend that you upgrade your pdns-recursor packages.
