UnknownEPSS 8.31%

Last modified

CVE-2002-2211 is a vulnerability of currently unknown severity. BIND 4 and BIND 8, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods.. EPSS estimates a 8.31% chance of exploitation in the next 30 days.
