Title
A flaw in the "deny-answer-aliases" feature can cause an assertion failure in named
Summary
"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to experience an assertion failure in name.c. Affects BIND 9.7.0->9.8.8, 9.9.0->9.9.13, 9.10.0->9.10.8, 9.11.0->9.11.4, 9.12.0->9.12.2, 9.13.0->9.13.2.
Severity
7.5 (High)
CWE
- Accidental or deliberate triggering of this defect will cause a REQUIRE assertion failure in named, causing the named process to stop execution and resulting in denial of service to clients.
- Accidental or deliberate triggering of this defect will cause a REQUIRE assertion failure in named, causing the named process to stop execution and resulting in denial of service to clients. Only servers which have explicitly enabled the "deny-answer-aliases" feature are at risk and disabling the feature prevents exploitation.
