Official Description
OpenTTD 0.6.0 through 1.2.1 does not properly validate requests to clear a water tile, which allows remote attackers to cause a denial of service (NULL pointer dereference and server crash) via a certain sequence of steps related to "the water/coast aspect of tiles which also have railtracks on one half."
Technical Analysis
CVE-2012-3436 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
