Technical details
A stack-based buffer overflow in the iked IKE key-management daemon on SRX series firewalls can be triggered by an authenticated remote-access VPN client during the authentication and JIMS identity-publishing phases. The vulnerability allows an attacker with valid VPN credentials to execute arbitrary code with root privileges or trigger a denial of service. This requires authentication and network access to the VPN endpoint.
