Description dwfreed 2015-07-28 19:10:25 UTC
From the URL:

An error in the handling of TKEY queries can be exploited by an attacker for use as a denial-of-service vector, as a constructed packet can use the defect to trigger a REQUIRE assertion failure, causing BIND to exit.


Both recursive and authoritative servers are vulnerable to this defect.  Additionally, exposure is not prevented by either ACLs or configuration options limiting or denying service because the exploitable code occurs early in the packet handling, before checks enforcing those boundaries.


BIND 9 version 9.9.7-P2 and 9.10.2-P3 have been released to resolve this.

This probably isn't the place to discuss it, but it does seem odd for it to just disappear from 9.9 to 9.10. is still installed. If anything, rather than losing the IPv4 reverse zone for loopback they should have added the IPv6 reverse for loopback :). I considered opening a new bug but I'm just going to add them to my local config.
