A vulnerability in the OSPF version 2 (OSPFv2) feature of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to improper validation of OSPF updates that are processed by a device. An attacker could exploit this vulnerability by sending a malformed OSPF update to the device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Una vulnerabilidad en la característica OSPF versión 2 (OSPFv2) del software Cisco IOS XE podría permitir que un atacante adyacente no autenticado provoque que un dispositivo afectado se recargue inesperadamente, lo que resultaría en una condición de denegación de servicio (DoS). • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-ospf-dos-dR9Sfrxp • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

A vulnerability in the IKEv1 fragmentation code of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a heap overflow, resulting in an affected device reloading. This vulnerability exists because crafted, fragmented IKEv1 packets are not properly reassembled. An attacker could exploit this vulnerability by sending crafted UDP packets to an affected system. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: Only traffic that is directed to the affected system can be used to exploit this vulnerability. This vulnerability can be triggered by IPv4 and IPv6 traffic. Una vulnerabilidad en el código de fragmentación IKEv1 del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque un desbordamiento de almacenamiento dinámico, lo que provocaría la recarga del dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ikev1-NO2ccFWz • CWE-121: Stack-based Buffer Overflow •

A vulnerability in the IKEv1 fragmentation code of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a heap underflow, resulting in an affected device reloading. This vulnerability exists because crafted, fragmented IKEv1 packets are not properly reassembled. An attacker could exploit this vulnerability by sending crafted UDP packets to an affected system. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition.

A vulnerability in the IP packet processing of Cisco Access Point (AP) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of certain IPv4 packets. An attacker could exploit this vulnerability by sending a crafted IPv4 packet either to or through an affected device. A successful exploit could allow the attacker to cause an affected device to reload unexpectedly, resulting in a DoS condition. To successfully exploit this vulnerability, the attacker does not need to be associated with the affected AP. This vulnerability cannot be exploited by sending IPv6 packets. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-dos-h9TGGX6W • CWE-20: Improper Input Validation •

A vulnerability in the boot process of Cisco Access Point (AP) Software could allow an unauthenticated, physical attacker to bypass the Cisco Secure Boot functionality and load a software image that has been tampered with on an affected device. This vulnerability exists because unnecessary commands are available during boot time at the physical console. An attacker could exploit this vulnerability by interrupting the boot process and executing specific commands to bypass the Cisco Secure Boot validation checks and load an image that has been tampered with. This image would have been previously downloaded onto the targeted device. A successful exploit could allow the attacker to load the image once. The Cisco Secure Boot functionality is not permanently compromised. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-secureboot-bypass-zT5vJkSD • CWE-501: Trust Boundary Violation •
