| 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 9.9.7.x prior to 9.9.7-P3 are affected by multiple vulnerabilities :
- A denial of service vulnerability exists due to an assertion flaw that is triggered when parsing malformed DNSSEC keys. An unauthenticated, remote attacker can exploit this, via a specially crafted query to a zone containing such a key, to cause a validating resolver to exit. (CVE-2015-5722)
- A denial of service vulnerability exists in the fromwire_openpgpkey() function in openpgpkey_61.c that is triggered when the length of data is less than 1. An unauthenticated, remote attacker can exploit this, via a specially crafted response to a query, to cause an assertion failure that terminates named. (CVE-2015-5986)
* Note: This check solely relied on the banner of the remote DNS server to assess this vulnerability, so this might be a false positive.
