Hello Kurt, Steve, vendors,

Freeciv upstream has released 2.3.3 version correcting one security
issue:

A denial of service flaw was found in the way the server component 
of Freeciv, a turn-based, multi-player, X based strategy game, 
processed certain packets (invalid packets with whole packet
length lower than packet header size or syntactically valid
packets, but whose processing would lead to an infinite loop). A
remote attacker could send a specially-crafted packet that, when
processed would lead to freeciv server to terminate (due to memory
exhaustion) or become unresponsive (due to excessive CPU use).
