Description Andrej Nemec 2018-07-20 14:39:16 UTC

A vulnerability was found in wesnoth which allows arbitrary code execution by exploiting a vulnerability within the Lua scripting language engine which allows escaping existing sandbox measures in place and executing untrusted bytecode.

Wesnoth executes Lua code from untrusted local files either written by players 
or downloaded through a player content distribution server, as well as from 
data sent over the network in multiplayer games; thus this vulnerability is 
rather severe as it can be exploited remotely by malicious parties without the 
user's knowledge.
