What is CVE-2005-3409?

OpenVPN versions prior to 2.0.4 are susceptible to a denial of service vulnerability when operating in TCP mode. Remote attackers could exploit this flaw to trigger a segmentation fault by inducing the accept function call to return an error status. This situation leads to a null dereference in the exception handling, effectively causing the OpenVPN service to crash and disrupt connectivity for legitimate users. Proper updates to the software are recommended to mitigate this risk.
