[HUB] CVE-2015-5477: Security vulnerability in BIND


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.

To check whether the used version of BIND is vulnerable, visit the following pages:

Operators should take steps to upgrade to a patched version as soon as possible.
