CVE-2018-5741

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 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-2018-5736

CVE-2018-5736

CVE-2018-5736 is an ISC BIND vulnerability affecting versions 9.12.0 and 9.12.1. The issue is an error in the zone database reference counting that can trigger an assertion failure when a vulnerable server performs several slave-zone transfers in quick succession (for example after valid NOTIFY m...

CVE-2017-3136 An error handling synthesized records could cause an assertion failure when using DNS64 with "break-dnssec yes;"

A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate. An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were...

CVE-2018-5741

CVE-2018-5741 concerns ISC BIND 9 and its update-policy feature for Dynamic DNS (DDNS). The issue stems from incorrect documentation of krb5-subdomain and ms-subdomain rule types in the Administrator Reference Manual, which could lead operators to believe their configured policies are more restri...

CVE-2017-3145

CVE-2017-3145 affects BIND: the resolver incorrectly sequenced cleanup operations on upstream recursion fetch contexts, causing a use-after-free that can trigger an assertion failure and crash named. Affected versions include BIND 9.0.0 through 9.8.x, 9.9.0–9.9.11, 9.10.0–9.10.6, 9.11.0–9.11.2, 9...

CVE-2017-3138

named contains a feature which allows operators to issue commands to a running server by communicating with the server process over a control channel, using a utility program such as rndc. A regression introduced in a recent feature change has created a situation under which some versions of name...

CVE-2018-5737

A problem with the implementation of the new serve-stale feature in BIND 9.12 can lead to an assertion failure in rbtdb.c, even when stale-answer-enable is off. Additionally, problematic interaction between the serve-stale feature and NSEC aggressive negative caching can in some cases cause...

CVE-2017-3136

A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate. An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were...

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-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-2017-3143

The CVE-2017-3143 issue is a TSIG authentication bypass in ISC BIND that could allow an attacker who can communicate with an authoritative DNS server and knows a valid TSIG key name to manipulate BIND into accepting an unauthorized dynamic update. The vulnerability affects multiple BIND releases ...

CVE-2017-3141 Windows service and uninstall paths are not quoted when BIND is installed
