Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200603-11
(Freeciv: Denial of Service)

Luigi Auriemma discovered that Freeciv could be tricked into the
allocation of enormous chunks of memory when trying to uncompress
malformed data packages, possibly leading to an out of memory condition
which causes Freeciv to crash or freeze.

Impact :

A remote attacker could exploit this issue to cause a Denial of
Service by sending specially crafted data packages to the Freeciv game
server.

Workaround :

Play solo games or restrict your multiplayer games to trusted
parties.
