CVE-2015-5069: Infoleak
First published: Fri Jun 26 2015(Updated: )
Quoting from <a href="http://www.openwall.com/lists/oss-security/2015/06/25/2">http://www.openwall.com/lists/oss-security/2015/06/25/2</a> "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 <a href="https://access.redhat.com/security/cve/CVE-2015-5069">CVE-2015-5069</a>. Patch [4] is an additional patch, fixing the lowercase problem. Patch [4] is <a href="https://access.redhat.com/security/cve/CVE-2015-5070">CVE-2015-5070</a>.
