It was discovered that Bind incorrectly handled certain malformed responses to an ANY query. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service (CVE-2016-9131). It was discovered that Bind incorrectly handled certain malformed responses to an ANY query. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service (CVE-2016-9147). It was discovered that Bind incorrectly handled certain malformed DS record responses. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service (CVE-2016-9444). An error in handling certain queries can cause an assertion failure when a server is using the nxdomain-redirect feature to cover a zone for which it is also providing authoritative service. A vulnerable server could be intentionally stopped by an attacker if it was using a configuration that met the criteria for the vulnerability and if the attacker could cause it to accept a query that possessed the required attributes (CVE-2016-9778). It was discovered that Bind incorrectly handled rewriting certain query responses when using both DNS64 and RPZ. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service (CVE-2017-3135). Oleg Gorokhov discovered that in some situations, Bind did not properly handle DNS64 queries. An attacker could use this to cause a denial of service (CVE-2017-3136). It was discovered that the resolver in Bind made incorrect assumptions about ordering when processing responses containing a CNAME or DNAME. An attacker could use this cause a denial of service (CVE-2017-3137). Mike Lalumiere discovered that in some situations, Bind did not properly handle invalid operations requested via its control channel. An attacker with access to the control channel could cause a denial of service (CVE-2017-3138). Clément Berthaux discovered that Bind did not correctly check TSIG authentication for zone transfer requests. An attacker could use this to improperly transfer entire zones (CVE-2017-3142). Clément Berthaux discovered that Bind did not correctly check TSIG authentication for zone update requests. An attacker could use this to improperly perform zone updates (CVE-2017-3143).
