CVE-2006-0987
MediumExploitation Probability (EPSS)
Very high risk99th percentile - higher than 99% of all known CVEs
Summary
The default configuration of ISC BIND before 9.4.1-P1, when configured as a caching name server, allows recursive queries and provides additional delegation information to arbitrary IP addresses. This allows remote attackers to cause a denial of service (traffic amplification) via DNS queries with spoofed source IP addresses.
Risk Assessment
Attackers can use the DNS server for traffic amplification and launch a DDoS attack against a victim, causing link congestion and service unavailability. The organization may become an unwitting participant in the attack, potentially resulting in its IP addresses being blocked.
Recommendation
Disable recursion for external clients or restrict it to trusted networks using access control lists (ACLs). Update ISC BIND to version 9.4.1-P1 or later.

- CVE-2015-8705High
In buffer.c in ISC BIND 9.10.x before version 9.10.3-P3, when debug logging is enabled, remote attackers can cause a denial of service (REQUIRE assertion failure and daemon exit, or daemon crash) or possibly have unspecified other impact via OPT data or an ECS option.
- CVE-2015-8461High
A race condition in resolver.c in ISC BIND 9.9.8 before 9.9.8-P2 and 9.10.3 before 9.10.3-P2 allows remote attackers to cause a denial of service (INSIST assertion failure and daemon exit) via unspecified vectors.
- CVE-2015-5986High
In ISC BIND versions 9.9.7 before 9.9.7-P3 and 9.10.x before 9.10.2-P4, a vulnerability allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via a crafted DNS response.
