Several security issues have been discovered in wesnoth, a fantasy turn-based strategy game. The Common Vulnerabilities and Exposures project identifies the following problems: Daniel Franke discovered that the wesnoth server is prone to a denial of service attack when receiving special crafted compressed data. Daniel Franke discovered that the sandbox implementation for the python AIs can be used to execute arbitrary python code on wesnoth clients. In order to prevent this issue, the python support has been disabled. A compatibility patch was included, so that the affected campagne is still working properly.
