Vulnerability Summary

A vulnerability in ISC BIND could allow an unauthenticated, remote malicious user to cause a denial of service (DoS) condition on a targeted system. The vulnerability is due to an error in the nxdomain-redirect feature of the affected software. An attacker could exploit this vulnerability by sending a recursive query request to the targeted system. A successful exploit could cause BIND to exit and halt service to other clients, resulting in a DoS condition. ISC.org has confirmed the vulnerability and released software updates.
