Arch Linux Security Advisory ASA-201507-1

Severity: Low
Date    : 2015-07-03
CVE-ID  : CVE-2015-5069 CVE-2015-5070
Package : wesnoth
Type    : information leakage
Remote  : Yes
Link    : https://wiki.archlinux.org/index.php/CVE


The package wesnoth before version 1.12.4-1 is vulnerable to information


Upgrade to 1.12.4-1.

# pacman -Syu "wesnoth>=1.12.4-1"

The problem has been fixed upstream in version 1.12.4 (an incomplete fix
existed in version 1.12.3).




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.

CVE-2015-5069 and CVE-2015-5070 have been assigned to this
vulnerability. Version 1.12.3 included a fix for CVE-2015-5069 only,
remaining vulnerable to CVE-2015-5070. Versions 1.12.4 and 1.13.1
contain a more complete fix that addresses both.


A remote attacker might be able to get access to sensitive information,
including but not limited to a user-defined passphrase used to
authenticate uploads to the game's content server.
