CVE-2018-5740

"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, ...

CVE-2018-5738

Change 4777 introduced in October 2017 introduced an unforeseen issue in releases which were issued after that date, affecting which clients are permitted to make recursive queries to a BIND nameserver. The intended and documented behavior is that if an operator has not specified a value for the...

CVE-2018-5736

An error in zone database reference counting can lead to an assertion failure if a server which is running an affected version of BIND attempts several transfers of a slave zone in quick succession. This defect could be deliberately exercised by an attacker who is permitted to cause a vulnerable...

CVE-2016-9778

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...

CVE-2017-3141

CVE-2017-3142

An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name may be able to circumvent TSIG authentication of AXFR requests via a carefully constructed request packet. A server that relies solely on TSIG keys for protection wit...

CVE-2017-3140

If named is configured to use Response Policy Zones RPZ an error processing some rule types can lead to a condition where BIND will endlessly loop while handling a query. Affects BIND 9.9.10, 9.10.5, 9.11.0-9.11.1, 9.9.10-S1, 9.10.5-S1...

CVE-2017-3135

Under some conditions when using both DNS64 and RPZ to rewrite query responses, query processing can resume in an inconsistent state leading to either an INSIST assertion failure or an attempt to read through a NULL pointer. Affects BIND 9.8.8, 9.9.3-S1 - 9.9.9-S7, 9.9.3 - 9.9.9-P5, 9.9.10b1,...

CVE-2018-5741 Update policies krb5-subdomain and ms-subdomain do not enforce controls promised in their documentation

To provide fine-grained controls over the ability to use Dynamic DNS DDNS to update records in a zone, BIND 9 provides a feature called update-policy. Various rules can be configured to limit the types of updates that can be performed by a client, depending on the key used when sending the update...

CVE-2017-3143 An error in TSIG authentication can permit unauthorized dynamic updates

An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name for the zone and service being targeted may be able to manipulate BIND into accepting an unauthorized dynamic update. Affects BIND 9.4.0-9.8.8, 9.9.0-9.9.10-P1,...

CVE-2017-3142 An error in TSIG authentication can permit unauthorized zone transfers

An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name may be able to circumvent TSIG authentication of AXFR requests via a carefully constructed request packet. A server that relies solely on TSIG keys for protection wit...

CVE-2018-5734: Reachable Assertion

While handling a particular type of malformed packet BIND erroneously selects a SERVFAIL rcode instead of a FORMERR rcode. If the receiving view has the SERVFAIL cache feature enabled, this can trigger an assertion failure in badcache.c when the request doesn't contain all of the expected...
