A vulnerability in the implementation of the Intermediate System–to–Intermediate System (IS–IS) routing protocol functionality in Cisco IOS XR Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition in the IS–IS process. The vulnerability is due to improper handling of a Simple Network Management Protocol (SNMP) request for specific Object Identifiers (OIDs) by the IS–IS process. An attacker could exploit this vulnerability by sending a crafted SNMP request to the affected device. A successful exploit could allow the attacker to cause a DoS condition in the IS–IS process.

Cisco IOS XR through 4.3.2 on Gigabit Switch Router (GSR) 12000 devices does not properly check for a Bidirectional Forwarding Detection (BFD) header in a UDP packet, which allows remote attackers to cause a denial of service (line-card restart) via a crafted packet, aka Bug ID CSCuw56900. Cisco IOS XR hasta la versión 4.3.2 en dispositivos Gigabit Switch Router (GSR) 12000 no verifica adecuadamente para una cabecera Bidirectional Forwarding Detection (BFD) en un paquete UDP, lo que permite a atacantes remotos provocar una denegación de servicio (reinicio de tarjeta en línea) a través de un paquete manipulado, también conocida como Bug ID CSCuw56900. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160311-gsr http://www.securitytracker.com/id/1035314 • CWE-399: Resource Management Errors •
