CVE-2014-8500
HighSummary
BIND versions 9.0.x through 9.8.x, 9.9.0 through 9.9.6, and 9.10.0 through 9.10.1 do not limit delegation chaining, allowing remote attackers to cause a denial of service (memory consumption and named crash) via a large or infinite number of referrals.
Risk Assessment
Attackers can exploit this vulnerability to exhaust memory and crash the DNS server, leading to service availability interruptions.
Recommendation
It is recommended to update BIND to the latest version that includes security fixes limiting delegation chaining.

- 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.
