FreeBSD : OpenTTD -- Denial of service (server/client) via invalid read (373e412e-f748-11df-96cd-0015f2db7bde)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

The OpenTTD Team reports :

When a client disconnects, without sending the 'quit' or 'client
error' message, the server has a chance of reading and writing a just
freed piece of memory. The writing can only happen while the server is
sending the map. Depending on what happens directly after freeing the
memory there is a chance of segmentation fault, and thus a denial of
service.
