Description

BIND contains a flaw that may allow a malicious user to insert invalid records into a recursive DNS server cache. The issue is triggered by a flaw in the DNS protocol, which does not require sufficient randomness in selecting Query ID and UDP source port for queries to authoritative servers. It is possible that the flaw may allow an attacker to spoof a DNS response to a legitimate query resulting in a loss of integrity.
