CVE-2021-40114 – Multiple Cisco Products Snort Memory Leak Denial of Service Vulnerability

https://notcve.org/view.php?id=CVE-2021-40114

Multiple Cisco products are affected by a vulnerability in the way the Snort detection engine processes ICMP traffic that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper memory resource management while the Snort detection engine is processing ICMP packets. An attacker could exploit this vulnerability by sending a series of ICMP packets through an affected device. A successful exploit could allow the attacker to exhaust resources on the affected device, causing the device to reload. Múltiples productos de Cisco están afectados por una vulnerabilidad en la forma en que el motor de detección Snort procesa el tráfico ICMP que podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://lists.debian.org/debian-lts-announce/2023/02/msg00011.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-dos-s2R7W9UU https://www.debian.org/security/2023/dsa-5354 • CWE-401: Missing Release of Memory after Effective Lifetime CWE-770: Allocation of Resources Without Limits or Throttling •
