CVE-2016-8864 log

Severity High
Remote Yes
Type Denial of service
A defect in BIND's handling of responses containing a DNAME answer can cause a resolver to exit after encountering an assertion failure in db.c or resolver.c

During processing of a recursive response that contains a DNAME record in the answer section, BIND can stop execution after encountering an assertion error in resolver.c (error message: "INSIST((valoptions & 0x0002U) != 0) failed") or db.c (error message: "REQUIRE(targetp != ((void *)0) && *targetp == ((void *)0)) failed").

A server encountering either of these error conditions will stop, resulting in denial of service to clients.  The risk to authoritative servers is minimal; recursive servers are chiefly at risk.
