Descriptions

ISC BIND 9.0.x, 9.1.x, 9.2.0 up to 9.2.7, 9.3.0 up to 9.3.3, 9.4.0a1 up to 9.4.0a6, 9.4.0b1 up to 9.4.0b4, 9.4.0rc1, and 9.5.0a1 (Bind Forum only) allows remote attackers to cause a denial of service (exit) via a type * (ANY) DNS query response that contains multiple RRsets, which triggers an assertion error, aka the "DNSSEC Validation" vulnerability.

ISC BIND 9.0.x, 9.1.x, 9.2.0 hasta la versión 9.2.7, 9.3.0 hasta la versión 9.3.3, 9.4.0a1 hasta la versión 9.4.0a6, 9.4.0b1 hasta la versión 9.4.0b4, 9.4.0rc1 y 9.5.0a1 (solo Bind Forum) permite a atacantes remotos provocar una denegación de servicio (salida) a través de la respuesta a una consulta DNS tipo * (ANY) que contiene múltiples RRsets, lo que desencadena un error de aserción, también conocido como la vulnerabilidad "DNSSEC Validation".

As confirmed by vendor security advisories, two security issues exist in the DNS server BIND, versions up to 9.3.4. The first issue is a "use after free" vulnerability which allows remote attackers to cause a Denial of Service (DoS) via unspecified vectors that cause BIND to "dereference (read) a freed fetch context". The second issue allows remote attackers to cause a Denial of Service (DoS) via a type "*" (ANY) DNS query response that contains multiple resource record (RR) sets in the answer section, which triggers an assertion error. To be vulnerable you need to have enabled DNSSEC validation in the configuration by specifying "trusted-keys".
