| Detailed Description |
ISC BIND (Berkeley Internet Name Daemon) is a server utility that implements the DNS (domain name service) protocol. It is widely used on the Internet. According to its version number, BIND version 9.11.x prior to 9.11.0-P2 are affected by multiple vulnerabilities :
- A denial of service vulnerability exists in named due to a flaw that is triggered during the handling of a specially crafted answer packet in a response to an RTYPE ANY query. An unauthenticated, remote attacker can exploit this to cause an assertion failure and daemon exit. (CVE-2016-9131)
- A denial of service vulnerability exists in named in DNSSEC-enabled authoritative servers that is triggered during the handling of a query response that contains inconsistent DNSSEC information. An unauthenticated, remote attacker can exploit this to cause an assertion failure and daemon exit. (CVE-2016-9147)
- A denial of service vulnerability exists in named due to a flaw that is triggered during the handling of a specially crafted answer that contains a DS resource record. An unauthenticated, remote attacker can exploit this to cause an assertion failure and daemon exit. (CVE-2016-9444)
- A denial of service vulnerability exists in named in the nxdomain-redirect functionality that is triggered when handling a specially crafted query. An unauthenticated, remote attacker can exploit this to cause a REQUIRE assertion failure and daemon exit. (CVE-2016-9778)
* Note: This check solely relied on the banner of the remote DNS server to assess this vulnerability, so this might be a false positive.
