---|---|---|---|
2018-03-16 | CVE-2018-7544 | Use of Externally-Controlled Format String vulnerability in Openvpn A cross-protocol scripting issue was discovered in the management interface in OpenVPN through 2.4.5. | 9.1 |
2006-05-05 | CVE-2006-2229 | Denial-Of-Service vulnerability in Openvpn and Openvpn Access Server OpenVPN 2.0.7 and earlier, when configured to use the --management option with an IP that is not 127.0.0.1, uses a cleartext password for TCP sessions to the management interface, which might allow remote attackers to view sensitive information or cause a denial of service. | 4.0 |
2006-04-06 | CVE-2006-1629 | Remote Code Execution vulnerability in Openvpn and Openvpn Access Server OpenVPN 2.0 through 2.0.5 allows remote malicious servers to execute arbitrary code on the client by using setenv with the LD_PRELOAD environment variable. | 9.0 |
2005-11-02 | CVE-2005-3409 | Remote Denial Of Service vulnerability in Openvpn and Openvpn Access Server OpenVPN 2.x before 2.0.4, when running in TCP mode, allows remote attackers to cause a denial of service (segmentation fault) by forcing the accept function call to return an error status, which leads to a null dereference in an exception handler. | 5.0 |
2005-11-01 | CVE-2005-3393 | Remote Format String vulnerability in Openvpn and Openvpn Access Server Format string vulnerability in the foreign_option function in options.c for OpenVPN 2.0.x allows remote clients to execute arbitrary code via format string specifiers in a push of the dhcp-option command option. | 7.5 |
2005-08-24 | CVE-2005-2534 | Denial Of Service vulnerability in OpenVPN Same Client Certificate Race condition in OpenVPN before 2.0.1, when --duplicate-cn is not enabled, allows remote attackers to cause a denial of service (server crash) via simultaneous TCP connections from multiple clients that use the same client certificate. | 2.6 |
2005-08-24 | CVE-2005-2533 | Unspecified vulnerability in Openvpn OpenVPN before 2.0.1, when running in "dev tap" Ethernet bridging mode, allows remote authenticated clients to cause a denial of service (memory exhaustion) via a flood of packets with a large number of spoofed MAC addresses. | 2.1 |
2005-08-24 | CVE-2005-2532 | Denial Of Service vulnerability in OpenVPN Packet Decryption Failure OpenVPN before 2.0.1 does not properly flush the OpenSSL error queue when a packet can not be decrypted by the server, which allows remote authenticated attackers to cause a denial of service (client disconnection) via a large number of packets that can not be decrypted. | 5.0 |
2005-08-24 | CVE-2005-2531 | Denial Of Service vulnerability in OpenVPN Failed Authentication OpenVPN before 2.0.1, when running with "verb 0" and without TLS authentication, does not properly flush the OpenSSL error queue when a client fails certificate authentication to the server and causes the error to be processed by the wrong client, which allows remote attackers to cause a denial of service (client disconnection) via a large number of failed authentication attempts. | 5.0 |
