Title
An error in QNAME minimization code can cause BIND to exit with an assertion failure
Summary
A defect in code added to support QNAME minimization can cause named to exit with an assertion failure if a forwarder returns a referral rather than resolving the query. This affects BIND versions 9.14.0 up to 9.14.6, and 9.15.0 up to 9.15.4.
Severity
5.9 (Medium)
CWE
- An attacker who manages to deliberately trigger this condition on a server which is performing recursion can cause named to exit, denying service to clients.
