CVE-2016-9131

named in ISC BIND 9.x before 9.9.9-P5, 9.10.x before 9.10.4-P5, and 9.11.x before 9.11.0-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed response to an RTYPE ANY query.

named in ISC BIND 9.x before 9.9.9-P5, 9.10.x before 9.10.4-P5, and 9.11.x before 9.11.0-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed response to an RTYPE ANY query.

named in ISC BIND 9.x before 9.9.9-P5, 9.10.x before 9.10.4-P5, and 9.11.x before 9.11.0-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed response to an RTYPE ANY query.

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).

These are all security issues fixed in the bind-9.16.20-1.4 package on the GA media of openSUSE Tumbleweed.

This update for bind fixes the following issues:

• Fix a potential assertion failure that could have been triggered by a malformed response to an ANY query, thereby facilitating a denial-of-service attack. [CVE-2016-9131, bsc#1018700, bsc#1018699]

• Fix a potential assertion failure that could have been triggered by responding to a query with inconsistent DNSSEC information, thereby facilitating a denial-of-service attack. [CVE-2016-9147, bsc#1018701, bsc#1018699]

• Fix potential assertion failure that could have been triggered by DNS responses that contain unusually-formed DS resource records, facilitating a denial-of-service attack. [CVE-2016-9444, bsc#1018702, bsc#1018699]

• Fixed ldapdump to use a temporary pseudo nameserver that conforms to BIND's expected syntax. Prior versions would not work correctly with an LDAP backed DNS server. [bsc#965748]
