CVE-2019-12657 – Cisco IOS XE Software Unified Threat Defense Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12657
A vulnerability in Unified Threat Defense (UTD) in Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper validation of IPv6 packets through the UTD feature. An attacker could exploit this vulnerability by sending IPv6 traffic through an affected device that is configured with UTD. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition.

CVE-2019-12649 – Cisco IOS XE Software Digital Signature Verification Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-12649
A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability exists because, under certain circumstances, an affected device can be configured to not verify the digital signatures of system image files during the boot process. An attacker could exploit this vulnerability by abusing a specific feature that is part of the device boot process. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device. Una vulnerabilidad en la funcionalidad de Comprobación de Imagen del Software Cisco IOS XE, podría permitir a un atacante local autenticado instalar y arrancar una imagen de software malicioso o ejecutar archivos binarios sin firmar en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-iosxe-digsig-bypass • CWE-347: Improper Verification of Cryptographic Signature •
