Ignacio R. Morelle reports:
As mentioned in the Wesnoth 1.12.4 and Wesnoth 1.13.1 release announcements, a security vulnerability targeting add-on authors was found (bug #23504) which allowed a malicious user to obtain add-on server passphrases from the client's .pbl files and transmit them over the network, or store them in saved game files intended to be shared by the victim. This vulnerability affects all existing releases up to and including versions 1.12.2 and 1.13.0. Additionally, version 1.12.3 included only a partial fix that failed to guard users against attempts to read from .pbl files with an uppercase or mixed-case extension. CVE-2015-5069 and CVE-2015-5070 have been assigned to the vulnerability affecting .pbl files with a lowercase extension, and .pbl files with an uppercase or mixed-case extension, respectively.
