CVE-2018-0155 – Cisco Catalyst Bidirectional Forwarding Detection Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0155
A vulnerability in the Bidirectional Forwarding Detection (BFD) offload implementation of Cisco Catalyst 4500 Series Switches and Cisco Catalyst 4500-X Series Switches could allow an unauthenticated, remote attacker to cause a crash of the iosd process, causing a denial of service (DoS) condition. The vulnerability is due to insufficient error handling when the BFD header in a BFD packet is incomplete. An attacker could exploit this vulnerability by sending a crafted BFD message to or across an affected switch. A successful exploit could allow the attacker to trigger a reload of the system. This vulnerability affects Catalyst 4500 Supervisor Engine 6-E (K5), Catalyst 4500 Supervisor Engine 6L-E (K10), Catalyst 4500 Supervisor Engine 7-E (K10), Catalyst 4500 Supervisor Engine 7L-E (K10), Catalyst 4500E Supervisor Engine 8-E (K10), Catalyst 4500E Supervisor Engine 8L-E (K10), Catalyst 4500E Supervisor Engine 9-E (K10), Catalyst 4500-X Series Switches (K10), Catalyst 4900M Switch (K5), Catalyst 4948E Ethernet Switch (K5). • http://www.securityfocus.com/bid/103565 http://www.securitytracker.com/id/1040587 https://ics-cert.us-cert.gov/advisories/ICSA-18-107-05 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-bfd • CWE-388: 7PK - Errors CWE-755: Improper Handling of Exceptional Conditions •
CVE-2012-4622
https://notcve.org/view.php?id=CVE-2012-4622
Cisco IOS XE 03.02.00.XO.15.0(2)XO on Catalyst 4500E series switches, when a Supervisor Engine 7L-E card is installed, allows remote attackers to cause a denial of service (card reload) via malformed packets that trigger uncorrected ECC error messages, aka Bug ID CSCty88456. Cisco IOS XE v03.02.00.XO.15.0(2)XO en switches de la serie Catalyst 4500E, cuando está instalada la tarjeta Supervisor Engine 7L-E, permite a atacantes remotos provocar una denegación de servicio (recarga de la tarjeta) a través de paquetes erróneos que provocan un mensaje de error ECC incorrecto, también conocido como Bug ID CSCty88456. • http://osvdb.org/85821 http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120926-ecc http://www.securityfocus.com/bid/55701 http://www.securitytracker.com/id?1027573 https://exchange.xforce.ibmcloud.com/vulnerabilities/78886 • CWE-399: Resource Management Errors •
