Categoría:	Denial of Service
Título:	ISC BIND DoS Vulnerability (CVE-2016-2088)
Resumen:	ISC BIND is prone to a denial of service (DoS) vulnerability.
Descripción:	Summary: ISC BIND is prone to a denial of service (DoS) vulnerability. Vulnerability Insight: BIND 9.10 has preliminary support for DNS cookies (or source identity tokens), a proposed mechanism designed to allow lightweight transaction security between a querying party and a nameserver. An error in the BIND code implementing support for this optional feature permits a deliberately misconstructed packet containing multiple cookie options to cause named to terminate with an INSIST assertion failure in resolver.c if DNS cookie support is enabled in the server. Only servers with DNS cookie support enabled at build time can be affected by this defect. In servers which do not have DNS cookie support selected, any cookies encountered will be ignored as unknown option types. Vulnerability Impact: Servers which are built with DNS cookie support enabled are vulnerable to denial of service if an attacker can cause them to receive and process a response that contains multiple cookie options. Affected Software/OS: ISC BIND version 9.10.x through 9.10.3-P3. Solution: Update to version 9.10.3-P4 or later. CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
