Gentoo Linux Security Advisory GLSA 200908-02 – Dynamic Update packets can cause a Denial of Service in the BIND daemon. Matthias Urlichs reported that the dns_db_findrdataset() function fails when the prerequisite section of the dynamic update message contains a record of type ANY and where at least one RRset for this FQDN exists on the server. Versions less than 9.4.3_p3 are affected.
