Description


A vulnerability has been reported in ISC BIND, which can be exploited by malicious people to poison the DNS cache.

The vulnerability is caused due to BIND caching records from the data section of a response without proper DNSSEC verification when resolving recursive client requests with checking disabled (CD), but asking for DNSSEC records (DO).

Successful exploitation requires that recursive queries are enabled and that the nameserver performs DNSSEC validation for its clients. Authoritative-only nameservers are not affected.

The vulnerability is reported in versions 9.0.x, 9.1.x, 9.2.x, 9.3.x, 9.4.0 through 9.4.3-P3, 9.5.0, 9.5.1, 9.5.2, 9.6.0, and 9.6.1-P1.


Solution:
Update to version 9.4.3-P4, 9.5.2-P1, or 9.6.1-P2.
