CVSS: 7.5EPSS: 5%CPEs: 11EXPL: 0CVE-2019-6477 – TCP-pipelined queries can bypass tcp-clients limit
https://notcve.org/view.php?id=CVE-2019-6477
21 Nov 2019 — With pipelining enabled each incoming query on a TCP connection requires a similar resource allocation to a query received via UDP or via TCP without pipelining enabled. A client using a TCP-pipelined connection to a server could consume more resources than the server has been provisioned to handle. When a TCP connection with a large number of pipelined queries is closed, the load on the server releasing these multiple resources can cause it to become unresponsive, even for queries that can be answered auth... • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html • CWE-400: Uncontrolled Resource Consumption •

09 Oct 2019 — In BIND Supported Preview Edition, an error in the nxdomain-redirect feature can occur in versions which support EDNS Client Subnet (ECS) features. In those versions which have ECS support, enabling nxdomain-redirect is likely to lead to BIND exiting due to assertion failure.

https://notcve.org/view.php?id=CVE-2018-5743
25 Apr 2019 — By design, BIND is intended to limit the number of TCP clients that can be connected at any given time. The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value for most servers. Unfortunately, the code which was intended to limit the number of simultaneous connections contained an error which could be exploited to grow the number of simultaneous connections beyond this limit.

https://notcve.org/view.php?id=CVE-2018-5745
22 Feb 2019 — "managed-keys" is a feature which allows a BIND resolver to automatically maintain the keys used by trust anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm.

16 Jan 2019 — 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 information.
