Category:	Denial of Service
Title:	ISC BIND DNS64 and RPZ Denial of Service Vulnerability
Summary:	ISC BIND is prone to a denial of service vulnerability.
Description:	Summary: ISC BIND is prone to a denial of service vulnerability. Vulnerability Insight: The flaw exists due to using both DNS64 and RPZ to rewrite query responses, query processing can resume in an inconsistent state. Vulnerability Impact: Successful exploitation will allow remote attackers to cause an INSIST assertion failure (and subsequent abort) or an attempt to read through a NULL pointer. On most platforms a NULL pointer read leads to a segmentation fault (SEGFAULT), which causes the process to be terminated. Affected Software/OS: ISC BIND versions 9.8.8, 9.9.3-S1 through 9.9.9-S7, 9.9.3 through 9.9.9-P5, 9.9.10b1, 9.10.0 through 9.10.4-P5, 9.10.5b1, 9.11.0 through 9.11.0-P2 and 9.11.1b1. Solution: Update to ISC BIND version 9.9.9-P6 or 9.10.4-P6 or 9.11.0-P3 or 9.9.9-S8 or later. CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
