https://notcve.org/view.php?id=CVE-2017-12244
A vulnerability in the detection engine parsing of IPv6 packets for Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause high CPU utilization or to cause a denial of service (DoS) condition because the Snort process restarts unexpectedly. The vulnerability is due to improper input validation of the fields in the IPv6 extension header packet. An attacker could exploit this vulnerability by sending a malicious IPv6 packet to the detection engine on the targeted device. An exploit could allow the attacker to cause a DoS condition if the Snort process restarts and traffic inspection is bypassed or traffic is dropped. This vulnerability is specific to IPv6 traffic only. • http://www.securityfocus.com/bid/101119 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171004-fpsnort • CWE-20: Improper Input Validation •

A vulnerability in the detection engine reassembly of Secure Sockets Layer (SSL) packets for Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition because the Snort process consumes a high level of CPU resources. Affected Products: This vulnerability affects Cisco Firepower System Software running software releases 6.0.0, 6.1.0, 6.2.0, or 6.2.1 when the device is configured with an SSL policy that has at least one rule specifying traffic decryption. More Information: CSCvc58563. Known Affected Releases: 6.0.0 6.1.0 6.2.0 6.2.1. Una vulnerabilidad en el ensamblaje del motor de detección de los paquetes Secure Sockets Layer (SSL) para el software Cisco Firepower System podría permitir a un atacante remoto no autenticado provocar una condición de denegación de servicio (DoS) porque el proceso Snort consume un alto nivel de recursos de la CPU. • http://www.securityfocus.com/bid/97451 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170405-cfpw • CWE-400: Uncontrolled Resource Consumption •
