  "details" : [ "A memory leak in the tls-crypt-v2 client key extraction in OpenVPN 2.5.0 through 2.6.20 and 2.7_alpha1 through 2.7.4 allows remote attackers to cause a denial of service (memory exhaustion) via a flood of crafted packets", "A flaw was found in OpenVPN. A memory leak in the `tls-crypt-v2` client key extraction allows remote attackers to cause a denial of service (DoS). By sending a flood of specially crafted packets, an attacker can exhaust the system's memory, making the service unavailable." ],
  "statement" : "This vulnerability is rated as Important. A memory leak within the tls-crypt-v2 client key extraction mechanism of OpenVPN can be remotely triggered by an unauthenticated attacker. By sending a high volume of specially crafted packets, an attacker can exhaust system memory, leading to a denial of service for the OpenVPN service. This impact is significant due to the remote, unauthenticated nature of the attack.",
