CVE-2018-5740 A flaw in the "deny-answer-aliases" feature can cause an assertion failure in named

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

The BIND installer on Windows uses an unquoted service path which can enable a local user to achieve privilege escalation if the host file system permissions allow this. Affects BIND 9.2.6-P2-9.2.9, 9.3.2-P1-9.3.6, 9.4.0-9.8.8, 9.9.0-9.9.10, 9.10.0-9.10.5, 9.11.0-9.11.1, 9.9.3-S1-9.9.10-S1,...

CVE-2018-5738 Some versions of BIND can improperly permit recursive query service to unauthorized clients

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-2017-3137 A response packet can cause a resolver to terminate when processing an answer containing a CNAME or DNAME

Mistaken assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records could lead to a situation in which named would exit with an assertion failure when processing a response in which records occurred in an unusual order. Affects BIND...

CVE-2017-3135

ISC BIND 9 DNS64 and RPZ combined can crash the server. CVE-2017-3135 causes an assertion failure or NULL pointer dereference when query responses are rewritten with both DNS64 and RPZ enabled, leading to a denial of service.
