Description Stefan Cornelius 2015-06-26 10:55:26 UTC 
Quoting from http://www.openwall.com/lists/oss-security/2015/06/25/2
"Wesnoth implements a text preprocessing language that is used in conjunction 
with its own game scripting language. It also has a built-in Lua interpreter 
and API. Both the Lua API and the preprocessor make use of the same function 
(filesystem::get_wml_location()) to resolve file paths so that only content 
from the user's data directory can be read.

However, the function did not explicitly disallow files with the .pbl 
extension. The contents of these files could thus be stored in saved game 
files or even transmitted directly to other users in a networked game. Among 
the information that's compromised is a user-defined passphrase used to 
authenticate uploads to the game's content server.

This issue was found by Toom Lõhmus, then verified and fixed by Ignacio R. 
Morelle."

There have been two patches, [3] and [4]. Patch [3] did only take lowercase extensions
into account and was incomplete. Patch [3] is CVE-2015-5069.
Patch [4] is an additional patch, fixing the lowercase problem. Patch [4] is CVE-2015-5070.
